AI Email Writer

AI email writer that turns a few key points into a complete email with a subject line, or drafts a reply to an email you paste in.

Email Details

This AI email writer drafts a complete email, greeting and sign-off included, from the key points you type. In Compose mode you choose one of ten email types and a length of about 100, 200 or 350 words. The Reply tab answers an email you paste in, and both modes suggest a subject line.

How to use the AI email writer

Compose a new email

  1. Pick an Email Type, for example Follow-up Email or Cold Outreach.
  2. Fill in Recipient Name and Your Name (up to 100 characters each). Left blank, they become "the recipient" and "the sender" in the request.
  3. Write the Key Points to Include. This is the only required field.
  4. Choose a Tone and an Email Length, then click Write Email.

Reply to an email

  1. Open the Reply tab and paste the message into Original Email.
  2. Describe your Reply Intent in up to 200 characters, such as "accept the meeting but ask to move it to Thursday".
  3. Pick a Tone and click Write Email. The tool asks the model for a subject line that starts with "Re:".

Email types, tones and lengths

The ten types are Professional Introduction, Follow-up Email, Sales Pitch, Job Application, Partnership Proposal, Thank You Email, Apology Email, Meeting Request, Newsletter and Cold Outreach. Lengths are Concise (~100 words), Standard (~200 words, the default) and Detailed (~350 words).

I added the tone menu because an email to a client should sound different from an email to a developer. It offers Professional, Friendly, Formal, Persuasive and Casual, and I use it to loosen up drafts that read too formally.

Example: a follow-up email

Settings: Follow-up Email, recipient Dana, sender Sam, Friendly, Concise. Key points: "met at the Leeds trade show on Tuesday; send the price list she asked for; offer a 20-minute call next week". An illustrative result (the wording changes on every run):

Subject: The price list you asked for on Tuesday

Hi Dana,

It was good to meet you at the Leeds trade show on Tuesday.
As promised, I've attached our current price list.

If it would help, I'm happy to walk you through it on a
20-minute call next week. Let me know a day that suits you.

Best,
Sam

The page splits the reply: the subject goes into its own Subject Line box with a Copy Subject button, the body goes below it with a character count, and Copy takes the body only. Notice that the model wrote "I've attached", which only holds if you attach the file. Check lines like that before you send.

Limits of this AI email generator

  • The AI email writer produces text only. It does not connect to your mailbox or send anything, so paste the draft into your email client.
  • Each request is capped at 2,000 characters, including the tool's own instructions (174 to 180 characters for a reply, 320 to 342 for a new email before names). Key points can run to roughly 1,450 to 1,650 characters depending on the names, and in the Reply tab the pasted email and your intent together to about 1,800. Longer requests fail with "Validation failed".
  • The text goes from this site's server to an outside AI provider (Google's Gemma models first, then other providers if that fails), so leave out passwords and confidential details.
  • Each IP address can make 5 AI requests a minute across all the AI tools on this site.

For a long thread, paste the latest messages into the text summarizer first, so you can write your intent in a sentence.

How to write an email people answer

The model can only use what you give it, so the key points decide most of the result. Put the one thing you want the reader to do in the key points, with any date or deadline written out ("reply by Friday 14 March"). Give context the reader needs and the model cannot guess, such as where you met or which order number this is about.

Concise suits cold outreach and meeting requests; Detailed suits apologies and proposals that need reasons. After editing, a pass through the grammar checker catches slips, and how to edit AI content so it sounds human covers the phrases that make an email read as machine-written.

Frequently Asked Questions

Are my emails private?
Partly. This site does not save your details or the generated email to its database, but they do leave your browser. Write Email sends them to this site's server, which passes them to an outside AI provider (Google, Groq or Cerebras) and returns the draft. Each provider handles what it receives under its own terms, so leave out passwords and confidential details. The rate limiter also records your IP address.
Is the AI email generator free?
Yes. The AI email writer has no account, trial or word allowance. The only limit is 5 AI requests per minute per IP address, shared with the site's other AI tools, and each Regenerate click counts as a request. If you hit it, wait a minute and press Write Email again.
Why didn't the Subject Line box appear?
The page looks for a line that starts with "Subject:" in the model's reply. If it finds one, it moves that line into the Subject Line box and shows the rest as the body. If the model left the subject out or wrote it another way, the whole reply appears in the body instead. Press Regenerate or add your own subject.
Does the reply keep the original subject?
The tool asks the model for a subject in the form "Re:" followed by a subject it infers from the email you pasted. If your pasted text includes the original subject line, the model usually reuses it. Check it before sending, because your mail client may already add its own "Re:" when you hit reply.
Can this email writer write in other languages?
The tool's instructions are in English and there is no language setting. Models often answer in the language of the key points or the pasted email, but that is not guaranteed. If you need another language, say so in the key points or the reply intent, for example "write the reply in Spanish".
