The best free AI email writers in 2026 are Mailmeteor (a free AI writer inside Gmail, 50 emails a day), Rytr (10,000 free characters a month), QuillBot (free, with a 100-word paraphrasing cap) and Mailmodo's free web tool. Copy.ai no longer has a free plan. If you want AI to answer incoming email for you, eesel AI's email agent does that in Gmail or Outlook, with 100 free credits and then plans from $299/month.
What is an AI email writer?
An AI email writer is an intelligent assistant that uses artificial intelligence to compose emails. Users provide a simple prompt, such as "write a follow-up to a new lead," and the tool generates a complete draft. The underlying technology analyzes the request to determine the required content and tone. Key benefits include significant time savings, consistent grammar and tone, and a solid starting point for any email correspondence.
How did I choose the best free AI email writers?
I picked tools with a real free plan, usable drafts and an easy start, with no credit card upfront. Two entries now bend the first rule: eesel AI is a paid agent with a free starting plan, and Copy.ai has dropped its free plan.
- Truly free plan: The tool must offer a forever-free plan, not a limited-time trial. The free version needs to be functional for real-world tasks.
- High-quality output: The AI-generated text must be coherent, contextually appropriate, and sound human-written with minimal editing required.
- User-friendly interface: Tools were selected for their intuitive design and ease of use, allowing users to start immediately without a steep learning curve.
- Meaningful free features: The free plan needed to include core features, such as tone adjustment, to provide a comprehensive user experience.

The 6 best free AI email writers in 2026
Here's a closer look at each tool, what it does well, where it falls short, and who should be using it.
1. eesel AI email agent
eesel AI is on this list for a different job: it answers the email for you instead of helping you write it. It's an AI email agent that connects through the Gmail integration or Outlook integration and starts when a new email arrives. It reads the thread, answers from your docs and help center, then leaves a draft for review or sends the reply. It can also label and archive mail. The same support agent works from a forwarding inbox, a helpdesk, Slack and Microsoft Teams. I walk through the setup in AI email agent for Gmail.
eesel also makes the eesel AI blog writer, at $4 per blog post, if what you need is content worth sending. I compare it with other free AI writers separately.
- Pros: It does the work after the email arrives: it reads the thread, answers from your docs, and drafts or sends the reply in Gmail or Outlook. Each action can run on its own or wait for a person to approve it.
- Cons: It isn't a free writing tool. It's built for teams answering a steady flow of similar emails, not for dashing off one-off messages, and it works one mailbox per connection.
- Pricing: The free plan has 100 credits, no card needed. Paid plans start at $299 per month for 500 credits, one credit per ticket or chat.
2. Mailmeteor
Mailmeteor is an AI assistant that integrates directly into your inbox and is designed for sending personalized emails at scale. It's used by over 7 million people and is recognized by Google. Its mail merge feature allows you to send customized campaigns straight from a Google Sheet. It is also built with privacy in mind, sending emails without needing to read your inbox.
- Pros: The free plan is quite generous, letting you send up to 50 emails a day. It's straightforward and respects your privacy.
- Cons: The AI assistant is currently only available for Gmail, so it does not currently support Outlook or Zoho users. Its mail merge does work with Outlook and other SMTP accounts.
- Pricing: There's a free plan. Paid plans start at $5.99 per user per month for Starter, and paying yearly gets you three months free.
3. QuillBot
QuillBot is a comprehensive writing toolkit rather than just a text generator. It includes ten different tools, such as its well-known Paraphraser, Grammar Checker, and Summarizer. Its primary strength is in polishing and improving existing text. With 6M+ users on its Chrome extension, it works across various platforms, from Gmail to Google Docs.
- Pros: The collection of tools provides a full suite for refining writing. The popular Chrome extension makes its features easily accessible.
- Cons: The free plan has notable restrictions. The Paraphraser is capped at 100 words at a time, and the Summarizer has a limit of 1,200 words, which may be restrictive for longer emails or documents.
- Pricing: A free plan is available. QuillBot Premium is $8.33 per month billed annually ($99.95 a year) or $19.95 billed monthly, with unlimited words in the Paraphraser and more advanced features.
4. Rytr
Rytr is a flexible and highly affordable AI writer well-suited for various types of short-form content. It offers over 40 use cases, allowing users to create everything from ad copy to email subject lines. The interface is clean and simple, enabling you to select a template, add context, and generate text quickly. Rytr now calls itself an AI relationship manager and follow-up assistant, with the writer living on as its Create tool.
- Pros: The free plan is a solid starting point, and its paid plans are among the most competitively priced available. It also supports over 30 languages, which is beneficial for global teams.
- Cons: The free plan's limit is based on characters (10,000 per month), and this limit can be reached quickly when writing longer pieces.
- Pricing: There's a free plan. Paid plans start at just $9 per month for Lite, with Personal at $19 and Pro at $49.
5. Mailmodo
Mailmodo positions itself as a way to run email marketing on autopilot with AI. Its free AI Email Writer allows for specific inputs, including campaign type, audience, and creative themes. A standout feature is its ability to create interactive AMP emails that people can use directly in their inbox, which can improve conversion rates. The platform is also SOC 2 and GDPR compliant.
- Pros: The level of marketing-specific detail is beneficial. Generating entire email strategies and interactive content from a prompt is a significant advantage for marketers.
- Cons: It's a web-based tool focused on building campaigns, so it may not be ideal for users who need a simple assistant for daily email replies.
- Pricing: The free AI Email Writer tool is available. The full marketing platform starts at $27/month (billed annually).
6. Copy.ai
Copy.ai is a GTM AI Platform built to accelerate sales and marketing work. It helps teams create consistent copy for ads, social media, and sales outreach using "Workflows." Its chat interface is designed specifically for go-to-market tasks. It is also SOC 2 compliant, meeting high security standards.
- Pros: It's designed for sales and marketing teams, with features that help create on-brand copy quickly and consistently.
- Cons: Copy.ai no longer lists a free plan, and its old free plan article now lands on a knowledge base index. The free route left is its web tools, like the cold email generator.
- Pricing: There's no free plan now. The paid "Chat" plan for small teams starts at $29 per month, or $24 per month billed annually.
Pro tips for using free AI email writers
Whichever tool you choose, follow these simple tips to get better results.
Pro tip
Be specific with your instructions. The AI's output is only as good as your prompt. Tell it who the email is for, what your goal is, the key points to include, and the tone you're going for.
Pro tip
Treat the output as a first draft. Always read through and edit what the AI gives you. Add your own personal touches, check the facts, and tweak the language to make sure it sounds like you.
Pro tip
Use it as an assistant, not a replacement. These AI writing tools are designed to help you get started and write faster, not to take over completely. Your judgment remains the most important part of the process.
Pro tip
Experiment with different tones. Most tools let you choose a tone like 'formal,' 'friendly,' or 'persuasive.' Try generating a few versions to see which one fits your message best.
What if you want AI to handle the email, not just help write it?
Every tool above helps you write. If the same questions land in your inbox every day, the bigger win is an agent that answers them. eesel AI connects to Gmail or Outlook and starts when a new email arrives. It reads the thread, answers from your docs and help center, then leaves a draft for review or sends the reply. It can also label and archive mail, and it works from a forwarding inbox, a helpdesk, Slack and Microsoft Teams. The Outlook setup is in AI email agent for Outlook.
The free plan has 100 credits, then plans start at $299/month for 500 credits. You can try it free. If what you're missing is something worth sending, the eesel AI blog writer reached 750k+ monthly impressions for eesel, at $4 per blog post.
