I Tested 20+ Best AI Email Generators: Here Are My Top Picks

I tested over 20 top AI email generators from cold email coaches to full-blown AI text generators and picked the 14 best that speed up my email writing. 

This guide breaks down what each one does best so you can find the perfect fit for your inbox.

What is an AI email generator?

An AI email generator is a software tool that uses artificial intelligence, particularly large language models, to draft, rewrite, and personalize emails. 

Most AI email generators leverage natural language processing (NLP) like GPT-4.1 and machine learning (ML) to generate email content that is coherent, contextually relevant, and tailored to specific needs.

These tools are built to take the blank page off your hands. Whether you need to draft cold outreach, respond to leads, or rewrite a follow-up in a more friendly tone, AI email generators focus purely on writing.

But here’s the key difference. 

While AI email assistants handle tasks like inbox sorting, calendar integration, and CRM syncing, email generators are laser-focused on content creation. They don’t manage your inbox, but they help you write smarter, faster, and with a better tone.

At their core, email generators exist to take what’s in your head and turn it into polished, professional email copy in seconds.

So, if you're just looking to write better emails, not manage them, AI email generators are your go-to.

1. Lindy: Best AI Sales Email Generator With Automated Workflows

What does it do? Lindy lets you build custom AI agents (“Lindies”) that handle everything from email writing and triage to lead gen and CRM updates.

Who is it for? Freelancers, as well as sales, marketing, and support teams looking to automate inbox tasks and personalize outreach at scale.

We built Lindy to make AI agents genuinely useful in your daily business operations. It’s not just another assistant that spits out emails. 

With Lindy, you don’t just write faster, you work BETTER.

From scheduling meetings to sending perfectly-timed follow-ups, our Lindies handle repetitive tasks so you can stay focused on the real work.

Like, you can use a Meeting Notetaker, Lindy. 

It’ll auto-join Zoom calls, transcribe them, summarize key action items, and draft a follow-up email, all before you’ve closed your laptop. 

And you get final approval before anything goes out.

The magic isn’t just in follow-ups. Lindie's extracts data from your CRM, calendar, and inbox, letting you generate custom outreach emails and answer client questions, without switching tabs. 

You can even give Lindy prompts like “Write a sales email for X” or “Summarize this customer thread,” and with your tone and context in mind, Lindy will generate a draft in seconds.

Lindies can collaborate too. One does the triage, another launches personalized sequences, and a third sends negotiation follow-ups using Lindy Mail and Email Negotiator templates. 

Pros

• Templates for Lead Generation
• Lindy Academy for in-depth tutorials 
• End-to-end automation from meeting notes to follow-ups
• Integrates over 4,000 apps via Apify and another 2,500 through Pipedream

Cons

• Might require initial setup to train each Lindy properly

Pricing

• Free plan:  400 tasks/month, 1M character knowledge base
• Pro ($49.99/month): 5,000 tasks/month, access to call features, 20M character knowledge base
• Business ($299.99/month):  30,000 tasks/month, premium phone call automation, priority support

2. MailMaestro: Best for fast Gmail and Outlook replies

What does it do? It helps you draft and reply to emails using AI inside Gmail and Outlook.

Who is it for? Busy professionals who want faster, smarter email replies without typing everything out.

MailMaestro is an AI email generator that lives right inside your Gmail or Outlook inbox. 

Once you install the Chrome extension, you’ll see a new AI-powered compose and reply feature built directly into your email window. 

To test this, I typed prompts like “Follow up on the proposal” or “Ask for a meeting,” and MailMaestro generated a full email draft with the subject line included. 

You even get multiple versions to choose from, so it feels like a SMART brainstorming buddy for your inbox.

MailMaestro also helped me with replies. 

For any incoming email, you can click the AI reply button to get a quick summary of the thread and several ready-to-send responses. 

This is especially helpful for managing sales conversations or client updates. 

It even recognizes your name and personal links (like your Calendly) after a bit of use.

That said, it doesn’t truly learn your tone or evolve. 

You won’t get a personalized writing style, but you do get smart, fast email support that saves time. It’s simple, efficient, and a step up from generic email templates.

Pros

• Integrates with tools like Gmail and Outlook 
• Supports multiple languages for global communication
• Built-in tone selector to match the message to your audience
• Prompt history lets you revisit and reuse past AI-generated drafts

Cons

• Requests access to sensitive data like browsing history
• AI suggestions often need minor tweaks to match your exact tone

Pricing

• Free Plan ($0/month):  Access to top AI models (GPT-4o, Claude 3.5), compose, reply, magic templates, and AI personality features.
  ‍
• Professional Plan ($15/month):  Unlimited AI usage, email summaries, smart scheduling, reminders, and watermark removal.
  ‍
• Team Plan ($15/month):  Includes Pro features plus template sharing, team dashboard, MS Teams support, and license management.

3. Copy.ai: Best for quick marketing content drafts

What does it do? Copy.ai generates marketing content like emails, product descriptions, and social posts using AI.

Who is it for? Marketers, founders, and freelancers who need quick, readable content without starting from scratch.

Copy.ai is like a fast, idea-generating tool for your content workflow. 

I used it to create product descriptions and email copy. Just pick a template, type in a few product details, and the AI writes out a draft in seconds. 

The tone is usually solid, especially for marketing-style writing that needs to sound polished but not robotic.

Copy.ai quickly generates structured content briefs, draft SEO-friendly copy that aligns with your brand’s aesthetics.

The real magic, though, is in its workflow templates. I tested one for generating product descriptions: it gave me polished blurbs, then added customer personas and ad copy angles.

 It’s a neat touch if you’re trying to brainstorm messaging QUICKLY.

There’s also a chat-based interface (like ChatGPT) where you can ask Copy.ai to summarize, rewrite, or generate from scratch. 

On the downside, you’ll often need to edit the copy to avoid sounding generic or accidentally lifting content too close to web results. 

Copy.ai isn’t a final-draft tool, it’s more of a structured first draft. 

Pros

• Translation and localization at scale
• Helps generate content for ABM campaigns
• Supports sales, marketing, and ops workflows
• Offers templates for prospecting and forecasting

Cons

• Paid plans are on the pricier side for solo users
• AI-generated text might need plagiarism checks and rewording

Pricing

• Free Plan ($0/month):  2,000 words/month, access to GPT-3.5 and Claude 3, basic templates, brand voice memory.
• Starter Plan ($49/month):  Unlimited words, unlimited chat projects, access to the newest LLMs, private community.

4. Jasper AI: Best for brand-consistent campaign writing

What does it do? Helps teams create branded marketing content using AI.

Who is it for? Marketers, content teams, and agencies managing multiple brands or campaigns.

Jasper AI is designed to help marketers create consistent, high-quality content faster.

I used it to write blog posts, product descriptions, ad copy, and email campaigns, all while keeping the tone aligned with brand guidelines. 

I like how Jasper prioritizes brand voice. 

You can define it upfront, which makes it easier to keep your tone consistent across blog posts, emails, ads, and other content types.

The Creator plan includes one user seat, Jasper Chat, SEO mode, and browser extension support. It’s suitable for individual marketers or small teams who need an everyday writing tool. 

When I tested the Pro plan, I could manage multiple brand voices, create and edit visual assets, and organize content for different clients or products using campaign templates.

It took some time to learn how to write clear prompts, but once I got the hang of it, Jasper made my workflow more EFFICIENT. 

The interface is clean, and the support resources are helpful if you get stuck. 

And while the integrations aren’t as rich as Lindy's, Jasper still connects with tools like Google Docs, HubSpot, Webflow, and Surfer SEO. 

But Jasper gives you enough connectivity to draft, optimize, and publish content without leaving your workflow.

Pros

• Jasper API for integrations
• Browser extension for on-the-go tasks
• Supports CCPA and GDPR compliance
• SEO and image editing tools are included in Pro
• Campaigns and templates speed up content creation

Cons

• Steep learning curve for first-time users
• Some templates need trial and error to fine-tune

Pricing

• Creator Plan ($49/month/seat):  1 seat, 1 brand voice, SEO mode, Jasper Chat, browser extension.
• Pro Plan ($69/month/seat):  Up to 5 seats, 3 brand voices, knowledge assets, image tools, campaign builder, user management.

5. Rytr: Best for affordable, everyday writing tasks

What does it do? Rytr helps you generate, edit, and rephrase content using AI.

Who is it for? Freelancers, students, and creators looking for a fast, lightweight AI writing tool.

Rytr is a quick, no-frills AI writing tool built for everyday content tasks. I used it for blog sections, social captions, product descriptions, and even email copy. 

What impressed me most is how DIVERSE the templates are. 

You can find over 40 use cases split across categories like creative writing, SEO, editing, and professional tools. 

As a content editor, I appreciate that Rytr includes practical tools like a grammar checker, sentence shortener, rewording tool, and primarily generators for job descriptions and business ideas.

For small writing jobs or brainstorming, Rytr performs well. 

The interface is clean, and the workflow is simple:  choose a use case, pick a tone and language, and add your input. 

You can even generate multiple variants, tweak creativity levels, and keep your drafts organized in folders. 

I also improved a product description using Rytr’s AI Bullet Point Generator. 

Though the results were fast, I had to tweak them a bit.

However, it’s not ideal for long-form projects or content that relies on context. There's no document-style editor. Still, for fast content generation on a budget, Rytr gets the job done.

Pros

• Plagiarism checks with the paid plans
• Rytr's Chrome extension for quick drafting
• Supports over 40 languages and 20 tone presets
• Tools for writing blog outlines and video descriptions

Cons

• Not suitable for research-heavy content
• Lacks advanced brand voice or style customization

Pricing

• Free Plan ($0/month):  10K characters/month, Chrome extension
• Unlimited Plan ($7.50/month):  Unlimited characters, 1 personal tone, 50 plagiarism checks/month
• Premium Plan ($24.16/month):  5 personal tones, 100 plagiarism checks/month, 40+ languages, tripled character input

6. ChatGPT: Best for flexible AI ideation and drafting 

What does it do? Helps you generate content, solve problems, and automate workflows using conversational AI.

Who is it for? Writers, marketers, developers, students, and anyone who works with ideas, communication, or planning.

I usually turn to ChatGPT when I need clarity fast, whether I’m drafting emails, planning campaigns, debugging code, or even outlining long-form content. 

It’s more than a chatbot. 

With GPT-4.5 and GPT-4o now available, it can write, summarize, translate, brainstorm, role-play, or walk you through complex topics with a level of depth that feels almost like a human co-creator.

I also used it to generate SEO-optimized blog sections, pitch ideas to clients, and even create custom cold emails for niche audiences by feeding it structured prompts. 

The catch is, you still need to be precise with your prompts.

You can refine outputs, ask for alternatives, and make the conversation adapt to your style or use case. 

Tools like custom instructions, GPTs (fine-tuned mini-bots), and prompt chaining take the FLEXIBILITY up a notch.

ChatGPT doesn’t always know what’s current, and it can sound overly confident about wrong facts unless you verify. 

It also follows strict content policies, which can limit how far you take certain conversations.

Plus, I did find it a bit frustrating when GPT started hallucinating while I was working on a buying guide for the best PDF editors.

Pros

• Great for brainstorming and idea expansion
• Adapts to multiple tones, formats, and use cases
• Custom instructions and GPTs add more flexibility
• Works well for both casual use and professional workflows
• Handles writing, planning, and problem-solving in one place

Cons

• May hallucinate or give outdated information
• Features like history and memory hit the limit on the free plan

Pricing

• Free Plan ($0/month):  Access to GPT-4o with usage limits, basic chat capabilities
  ‍
• ChatGPT Plus ($20/month):  Access to GPT-4o with higher usage limits, faster response times, priority access to new features, and additional tools like web browsing, file uploads, and image generation.
  ‍
• ChatGPT Team ($25–$30/user/month):  Includes all Plus features, shared workspace, admin console, and higher message limits for GPT-4o.
  ‍
• ChatGPT Pro ($200/month):  Unlimited access to advanced models such as OpenAI o1 and GPT-4o, advanced voice mode, and exclusive features like the o1 pro mode for enhanced problem-solving abilities

7. HubSpot: Best for CRM-powered marketing emails 

What does it do? Hubspot lets you build, personalize, and automate email marketing campaigns directly from your CRM.

Who is it for? Growing businesses, B2B marketers, and teams that want CRM-powered email campaigns.

I used HubSpot’s drag-and-drop builder to create a podcast promotion email and it handled everything from template selection to tracking performance, all within a few clicks. 

The real strength lies in how tightly it connects with HubSpot’s CRM. 

I could segment contacts, personalize messages using contact data, and trigger emails based on behavior, all without a bunch of tools.

HubSpot’s built-in AI helps generate subject lines and preview text based on your actual email content. 

You can also A/B test different versions, track where people click using heat maps, and monitor email health scores to fine-tune delivery and engagement over time.

One thing I liked was the ability to resurface contacts who didn’t click or open the first email and re-engage them using smart automation and list filters. 

Whether it’s static or active lists, HubSpot makes it EASY to segment and automate outreach.

I wouldn’t call it intuitive, though. 

The learning curve is there, especially if you’re new to CRM-based systems. 

But once you’re in, it’s a solid all-in-one platform for managing everything, from newsletters and sign-up forms to follow-up workflows and shared inbox replies.

Pros

• Customizable website traffic analytics
• Advanced SEO tools with full site audits
• Social media scheduling for up to 3 years
• Facebook Messenger integration with bot branching
• Unlimited subdomains and domain localization options

Cons

• Steep price jump when moving beyond the basic plan
• Some tools, like the social calendar, feel unintuitive and glitchy

Pricing

• Free Plan ($0/month):  Includes free marketing, sales, service, content, and CRM tools for up to 2 users
  ‍
• Marketing Hub Starter ($20/month/seat):  1,000 marketing contacts, removes HubSpot branding, live chat, email marketing, simple automation, in-app chat support
  ‍
• Starter Customer Platform ($20/month):  Includes everything in Starter plus sales, service, content, and operations hubs with 1,000 marketing contacts
  ‍
• Marketing Hub Professional ($890/month):  2,000 marketing contacts, 3 seats included, advanced automation, A/B testing, custom reporting, dynamic personalization, social media publishing.

8. SaneBox: Best for cleaning up email clutter 

What does it do? Cleans up your email inbox with smart filtering, snoozing, and automation.

Who is it for? Professionals, freelancers, and anyone overwhelmed by email clutter.

SaneBox is an email generator that helps you manage your inbox without switching apps.

I connected it to iCloud and Fastmail, and it started organizing emails within minutes. 

The setup is simple, and the custom training system ensured I didn’t miss any important messages. 

I really liked how the snooze feature let me SMOOTHLY move emails to folders like “SaneTomorrow” or “SaneNextWeek,” bringing them back to my inbox exactly when I need them.

Since it works within my existing email client, I didn’t have to learn a new interface or switch apps.

Other highlights include the “SaneLater” folder, which automatically filters out non-urgent emails, and the “SaneBlackHole,” which trains the system to delete emails from unwanted senders. 

You can also set up cloud attachments to auto-save files to Dropbox or Google Drive, and the Do Not Disturb feature lets you pause email delivery during specific hours.

The only downside is that there’s no free plan, though you do get a 14-day trial to test all the features.

Pros

• Supports Android, iOS, Windows, and Mac
• Offers strong privacy and doesn’t store your emails
• Daily email digest to review missed or filtered messages
• Great for batch email processing without overwhelming the UI

Cons

• Lack of live chat support
• The dashboard feels a bit dated compared to newer tools

Pricing

• Snack Plan ($3.49/month):  1 email account, 2 SaneBox features, email and chat support
• Lunch Plan ($5.99/month):  2 email accounts, 6 SaneBox features, email, chat, and phone support
• Dinner Plan ($16.99/month):  4 email accounts, all SaneBox features, full support via email, chat, and phone

9. Writesonic: Best for long-form SEO and blog posts 

What does it do? Helps you create full-length blog posts, ads, product descriptions, and more with AI.

Who is it for? Bloggers, content teams, marketers, and entrepreneurs looking to speed up content production.

Writesonic is one of those tools that feels built for creators with high output demands.

I tested it using its AI article writer and ended up with a surprisingly CLEAN, well-structured blog post in just minutes.

You start with a prompt and some optional keywords, and it drafts everything, from intro to conclusion. 

Unlike some clunky tools, I found it easy to switch tones, formats, or languages.

Templates are grouped by use case(ads, social posts, SEO, eCommerce), and the editor feels like a mini CMS, complete with formatting tools, link options, and direct publishing to WordPress. 

I found the SEO tools particularly helpful. 

I could run quick checks, spot content gaps, and even generate image assets for my posts without switching tools. 

And when I needed fast research or conversational replies, Chatsonic worked like a reliable software built right into the dashboard. 

You can even generate instant articles when you’re short on time or choose a step-by-step writing mode for more control. 

Unfortunately, the free credits don’t go far, so you’ll hit the paywall quickly if you're testing multiple features. Still, for polished content at speed, Writesonic delivers.

Pros

• Supports end-to-end workflow
• Integrates Ahrefs, Google Analytics, and WordPress
• Writesonic analyze PDFs, CSVs, and Drive files instantly
• Maintains consistent brand voice with custom tone training
• Offers multiple AI models, including GPT-4o, Claude, and Gemini

Cons

• Basic free trial
• Content quality can vary based on the model and template

Pricing

• Free Trial ($0/month):  Test all features with 1 project, 3 AI generations, and basic audits.
• Lite ($49/month):  Best for solo marketers. Adds more generations, audits, and 2 writing styles.
• Standard ($99/month):  Ideal for SEO professionals. Includes unlimited generations, SEO tools, and 5 writing styles.
• Professional ($249/month):  For small in-house teams. Adds more users, deeper site audits, and campaign tracking tools.
• Advanced ($499/month):  Built for agencies. Scales up users, audits, writing styles, and adds API access.

10. MailerLite: Best for email + landing page creation 

What does it do? MailerLite helps you design and automate email campaigns, landing pages, and forms, without any bloat.

Who is it for? Ideal for solo creators, small businesses, and teams who want a simple, affordable email marketing platform.

What I like most about MailerLite is how little effort it takes to get started. The interface is clean. A no-clutter, no complex onboarding. 

I created my first email campaign within minutes, and the drag-and-drop editor felt like second nature. It’s not trying to be everything, and that’s the beauty of it.

Automation is quite INTUITIVE.

I built welcome flows and post-signup sequences with simple triggers and actions. 

No jargon, no confusion. And even if you’re new to email marketing, the visual layout makes it easy to follow your customer’s journey.

One standout is the built-in landing page and form builder.

I didn’t need separate tools to collect emails or build a simple waitlist page. It also helped that I could manage everything (emails, new forms, subscribers) in one dashboard. 

MailerLite lets you spice up newsletters with e-commerce blocks, AI writing, surveys, RSS updates, and social sharing. 

I also liked its dynamic content filters to personalize emails better.

It’s not the most advanced tool, and if you’re looking for extensive integrations or behavioral segmentation, this might not cut it. But for most small setups, it’s more than enough. 

Pros

• Nonprofits get 30% off on all paid plans
• GDPR-compliant for secure subscriber data handling
• Easy-to-use website and blog builder. No coding needed
• Manage emails, forms, sites, and landing pages from one place

Cons

• Limited behavioral targeting and segmentation features
• Customer support can be slow or unresponsive during issues

Pricing

• Free ($0/month):  Supports up to 1,000 subscribers. Includes 12,000 monthly emails, 1 user, and access to essential tools like a drag-and-drop editor, forms, landing pages, and automation builder. Also comes with 30-day access to premium features.
  ‍
• Growing Business ($10/month):  For 500 subscribers. Adds 3 user seats, unlimited emails, advanced templates, automation options, and a landing page builder.
  ‍
• Advanced ($20/month):  Adds smart sending, Facebook integration, custom HTML editing, pop-ups, and other advanced marketing features. Includes unlimited user seats and 24/7 live chat support.

11. Google Gemini: Best for Gmail and calendar AI tasks 

What does it do? Gemini is Google’s AI assistant that helps you manage Gmail and Google Workspace tasks with smart, natural prompts.

Who is it for? Ideal for busy professionals and Google Workspace users looking to save time and organize email workflows.

Gemini lives right inside your Gmail inbox, and once you start using it, it kind of feels like having a SUPER-ORGANIZED tool on call. 

I used it to summarize email threads, search for old attachments, and even auto-draft replies, all without leaving Gmail.

What stood out is how well it talks to your other Google apps. 

Need to check your calendar availability or book a meeting? Just ask. I tested it with a simple “Do I have time between 1 and 3 PM tomorrow?” and it pulled my calendar data in seconds. 

Then, with one more prompt, it scheduled a meeting for me.

You can also locate and summarize Docs or Sheets from Google Drive, making it useful for context gathering before replying to emails. 

I even asked Gemini to write full email drafts for sales pitches, proposals, you name it, and it didn’t disappoint. 

You can fine-tune the tone or length, then drop it right into your reply. 

Most edits can be made directly in Canvas, too, which keeps the whole process smooth.

Gemini isn’t perfect with every prompt. I had to manually adjust an event’s duration when it misread the time. I found GPT more reliable for nuanced writing tasks, but Gemini holds its ground when it comes to real-time workspace actions. 

Pros

• Integration with Gmail and other Google Workspace apps
• Handy writing tool for email replies, proposals, and summaries
• Can summarize long threads or extract attachments via natural prompts
• Smart calendar support:  check availability, create/edit events without leaving Gmail

Cons

• Limited customization compared to standalone AI writing tools
• Currently best suited only for users deep in the Google ecosystem

Pricing

Free plan: Gemini is free for everyone with a Google account and includes access to Gemini 1.0 inside Gmail, Docs, Slides, and other Workspace apps. 

Gemini Advanced ($19.99/month): Includes Gemini 1.5 Pro, priority access to new features, and 2TB Google One cloud storage.

12. Mailmeteor: Best for Gmail mail merges and outreach

What does it do?  Mailmeteor lets you send personalized mass emails from Gmail, with basic AI drafting and campaign management features.

Who is it for? Best for solopreneurs, small teams, and educators who want simple mail merges and outreach directly from Gmail.

I tested Mailmeteor by connecting it to Gmail, and it was refreshingly SIMPLE to set up. 

I could create a campaign, import a list from Google Sheets, personalize the message with variables like first name, and schedule the emails, all without leaving my inbox.

The process of previewing, testing, and sending is smooth. It also includes click tracking, scheduling, unsubscribe links, and an “autopilot” mode for better deliverability. 

I liked the preview feature, which gave me a clean test run before I hit send. It doesn’t overcomplicate the basics.

That said, its AI features felt more like a side note than a core strength.

When I asked it to reply to emails in German, it worked fine, but it lacked context-awareness. 

Unlike Gemini or GPT-based tools, Mailmeteor doesn’t pull from your inbox history or understand nuance. The draft generation is functional, but generic.

If your goal is bulk, personalized emails without diving into complex CRM tools, Mailmeteor gets the job done. 

Just don’t expect it to write with much insight beyond what you type in. For AI-driven workflows and integrations, Lindy works way better.

Pros

• Clean UI, and beginner-friendly campaign flow
• Works directly inside Gmail, no need to switch tools
• Easy mail merge with Google Sheets or CSV imports
• Scheduling and autopilot features improve deliverability
• Includes personalization variables, unsubscribe links, and preview

Cons

• Requires high Gmail access permissions
• Limited customization beyond email content and timing

Pricing

• Hobby (Free):  Send up to 50 emails/day with 1 sender and 3 campaigns, ideal for testing the basics.
• Starter ($4.99/month):  5,000 emails/month, 5 campaigns, custom templates, and branding removal.
• Premium ($12.99/month):  15,000 emails/month, 15 campaigns, 3 senders, plus email tracking, Sheets automation, and Autopilot.
• Pro ($24.99/month):  45,000 emails/month, unlimited campaigns, 5 senders, with bounce detection, auto follow-up, and priority support.

13. Shortwave: Best for AI-powered Gmail task workflows

What does it do? Shortwave helps you manage email, tasks, and scheduling using built-in AI tools, all from a Gmail-integrated interface.

Who is it for? Busy professionals, founders, and small teams who want faster inbox management and lightweight task automation.

Shortwave feels like Superhuman and Notion had a Gmail-native baby. I used it primarily to declutter my inbox, and right off the bat, the bundling and AI-powered search felt snappy and accurate. 

You can split your inbox into categories like finance, newsletters, or team threads, and bulk triage them with one click.

The to-do system is SOLID, too. 

I turned emails into tasks with just a keystroke, and the AI-generated titles were usually spot-on. 

You also get scheduling tools that pull directly from your Google Calendar, so booking or adjusting meetings is a BREEZE. 

It’s not just about productivity. This AI tool helps write, summarize, and even auto-complete emails in your tone (if you’re on a paid plan).

I loved how I could ask it to schedule a call or summarize a thread and get what I needed without switching tabs.

The UI is sleek, but switching between tasks and emails can sometimes feel a bit jumpy, especially on slower networks. 

I also missed extensive formatting options while editing long emails. 

Compared to Gemini, Shortwave's AI search and bundling felt more tailored for everyday work, while Gemini felt more "general."

Pros

• Mute notifications with Do Not Disturb mode
• Share live threads with your team in real time
• Add private comments without leaving your inbox
• Use the command palette to take quick keyboard action

Cons

• Steeper learning curve if you're used to traditional inboxes
• Some features (like better autocomplete or AI filtering) are gated behind premium

Pricing 

• Free:  Organize, search, and schedule with AI. 90 days of AI search history and basic inbox features. 
• Personal ($8.50/month):  Unlimited AI search, inbox splits and bundles, custom themes, and no Shortwave branding.
• Pro ($18/month):  Real-time team collaboration, AI autocomplete, and advanced AI writing for up to 3 accounts.
• Business ($30/month):  Adds 3 custom filters, prompt saving, file analysis, and team read statuses.
• Premier ($45/month):  Unlimited search, 10 AI filters, live training, and top-tier AI performance with 2x tokens.

14. Lavender: Best for writing better cold sales emails 

What does it do? Helps you write better cold emails with real-time coaching and AI personalization.

Who is it for? Sales reps, SDRs, and email marketers looking to boost replies.

Lavender is built like a co-pilot for your sales emails, one that scores your draft in real time, pinpoints what needs fixing, and offers suggestions to improve it.

I tested it while cold-emailing a few leads, and the email scorecard kept nudging me to rewrite bulky lines, remove spammy phrasing, and even tweak my subject line.

It’s surprisingly MOTIVATING to keep editing when the score jumps from a 78 to a 91.

There’s a whole coaching system baked in, too. 

It highlights tone issues, poor formatting, or unclear CTAs and gives you a cleaner, high-performing version using pre-set best-practice frameworks.

I loved how Lavender QUICKLY extracted data about the recipient from past threads, social posts, CRM history, and even earnings reports. 

Then it helped me tailor a pitch that actually felt personalized, not just [first name] swaps.

You also get a web-connected GPT assistant right inside the app. 

At times, Lavender can be a little glitchy, especially during longer sessions. 

And while the AI rewrite tool is great for structure, it’s not as flexible as GPT-4.5. Still, if you're writing dozens of emails a day, it saves you a ton of time.

Pros

• Integrate with tools like Gmail, Outlook, Outreach, Salesloft, and HubSpot
• LavenderLand for interactive sales coaching
• Built-in frameworks for cold emails and follow-ups
• Email previews, mobile readability checks, and spam detection

Cons

• Customer support could be more hands-on
• Limited standalone writing features compared to full AI tools like Lindy

Pricing

• Free Forever:  Analyze 5 emails/month with basic scoring, Gmail/Outlook support, and AI summaries.
• Starter ($29/month):  Adds unlimited email scoring, mobile optimization, and personalization.
• Individual Pro ($49/month):  Unlocks all integrations, priority support, and unlimited rewriting.
• Team Plan ($99/seat/month):  Includes coaching dashboards, API access, and advanced analytics for sales teams.

How I tested the best AI email generators

The best AI email generators in 2025 aren’t just about writing a nice message; it’s the ones that:

• Draft replies that sound like you
• Helps organize or triage emails automatically
• Connects with your tools like CRM, calendar, or workspace tools
• Saves hours when you're replying to dozens of messages a day

To separate the hype from the helpful, I spent weeks testing over 20 AI email tools using the same hands-on criteria:

• Real-World Email Drafting: I didn’t just click around; I sent real emails. From cold outreach to warm follow-ups, I tested how well each tool handled tone, structure, and context. I paid attention to personalization: could it pull in relevant details from the inbox, or did it just swap in {first_name}?
  ‍
• Workflow Automation: A few tools were just writing helpers. Others felt like full-on productivity systems. I tested how each tool handled the full lifecycle, like triaging, scheduling, follow-ups, or even logging info back into a CRM. Bonus points if it saved me clicks.
  ‍
• Ease of Use & Integration: The Setup time varied a lot. I documented how long it took to go from install to inbox-ready, how intuitive the UI felt, and which platforms (like Gmail, Outlook, Notion, HubSpot) each tool played nicely with.

And after all that? A few tools genuinely changed how I work. Especially Lindy, which stood out as the most flexible and full-featured AI tool I tested.

Can An Email Assistant Improve my Workflow?

Yes, a better email assistant could significantly enhance your workflow by improving communication, boosting productivity, and potentially leading to more effective workflows. 

Tools like Lindy go beyond drafting emails; they automate follow-ups, qualify leads, and even update your CRM, giving you back hours every week to focus on the work that actually moves the needle.

Frequently Asked Questions

1. Which is the best AI email generator for cold outreach

Lindy is the AI email generator for cold outreach if you want a fully automated system that writes, sends, and follows up on cold emails while syncing with your CRM and calendar tools. Apart from just writing email, it can automate a lot of other parts of your email campaign that no other email automation tool can do. 

2. How do AI email generators work

AI email generators use natural language processing (NLP) and machine learning (ML) to understand your input, analyze it, and generate coherent email content.

Many tools also let you tweak the tone, personalize with variables, or generate multiple options to choose from.

3. Is it safe to use AI email tools with Gmail or Outlook

Yes, most leading AI email tools are designed with user security in mind. They encrypt your data, comply with privacy regulations like GDPR, and don’t store your messages permanently. 

Still, it is a good idea to review the access permissions they request, especially if they ask to read, send, or manage your emails directly.

4. Can AI tools write emails in my personal tone

Yes, many tools today let you customize your tone. Jasper and Lindy offer brand voice training so your messages stay consistent across emails and campaigns. ChatGPT and similar tools adapt through prompt engineering, letting you guide the tone and structure of every draft.

5. What makes Lindy different from other email generators

Lindy does more than write emails. It lets you build AI agents called Lindies that can handle email writing, CRM updates, meeting notes, and follow-ups. These agents pull data from your tools, automate repetitive tasks, and keep everything in context so your communication feels personal and professional.

6. Do I need a CRM to use AI email tools effectively

You can use most AI tools without a CRM, but having one adds a lot of value. CRM integration helps personalize emails based on contact data, automate outreach flows, and track performance. Tools like HubSpot and Lindy work best when paired with CRM systems to create powerful end-to-end workflows.

7. Is the free plan enough for daily email use

Yes, free plans are great for casual users or early testing. However, they often have usage limits and fewer features. If you write and send emails regularly or need templates, automation, and integrations, upgrading to a paid plan is usually worth the investment for the time it saves.

8. Can AI email tools support multiple languages

Yes, most modern AI email tools support multilingual content creation. Tools like Rytr and Copy.ai can write and translate emails in over 40 languages, which makes them ideal for global teams, international outreach, or customer support across different regions.

9. Can AI automate full email workflows

Yes, advanced tools like Lindy can handle everything from writing and sending emails to summarizing meetings, setting reminders, and managing follow-ups. You can create custom workflows that reduce manual effort and keep your inbox organized without needing to switch between apps constantly.

10. What is the best AI tool for Gmail users

Google Gemini is a great choice if you’re using Gmail or Google Workspace. It sits inside Gmail and connects with other Google apps to summarize emails, write replies, find documents, or schedule meetings. It feels like having a built-in tool that understands your entire workspace.

11. Can AI fully replace manual email writing

No. AI tools are powerful, but they still need human judgment. They’re best used for drafting and organizing, not for replacing your voice entirely. The best tools, like Lindy, offer a balance where you get the speed of automation with full control over final approval and tone.
