Free AI Email Generator Say What Happened, Get the Email
Describe who you are writing to and what you need from them. The AI email writer drafts the message with a subject line, and you adjust the tone, length or details in the same chat until it is ready to send.
Emails people ask for
Six emails that are hard to start and easy to get wrong. Each card ends with a prompt you can copy into the box below and finish with your own details.
You sent something a week ago and heard nothing. A good follow-up is short, restates the one thing you need and makes it easy to answer.
Prompt: "Write a polite follow-up to an email I sent 7 days ago about [topic]. Keep it under 80 words and end with one clear question."
Writing to someone who does not know you. It has to say who you are, why them, and what you want, in that order, before they stop reading.
Prompt: "Write a cold email to [role] at [company]. I am [who you are]. I want [the ask]. One reason it is relevant to them: [reason]."
A late order, a wrong charge, a service that did not show up. State the facts, the dates and the fix you expect, without venting.
Prompt: "Write a firm complaint to [company] about [problem]. Order number [number], date [date]. I want [refund, replacement, fix] by [date]."
You missed a deadline or made a mistake. A good apology names what went wrong, does not make excuses, and says what happens next.
Prompt: "Write a short apology to [person] for [what happened]. Take responsibility, skip the excuses, and say what I will do to fix it."
Time off, a raise conversation, a deadline extension, an introduction. The ask should be in the first two sentences, with the reason right after.
Prompt: "Write an email asking my manager for [request]. Reason: [reason]. Keep it professional and suggest a time to talk."
Paste the email you received and say what you want to answer: yes, no, not yet, or a question back. The reply matches the thread's tone.
Prompt: "Here is an email I received: [paste]. Write a reply that says [your answer]. Match their tone and keep it brief."
The more real details you give, the less the email sounds generated. Names, dates, order numbers and the one thing you want are what turn a template into your email. Leave placeholders in brackets if you would rather fill them in yourself.
From situation to sent in four steps
What to put in the message so the first draft is close to the final one.
A client, your manager, a landlord, a stranger on LinkedIn. The relationship decides how formal the email should be.
One outcome: a reply, a meeting, a refund, a yes. An email that asks for three things usually gets none of them.
Dates, amounts, names, what already happened. The AI only knows what you tell it and will leave gaps or guess if you skip them.
Ask for shorter, warmer, firmer or less stiff. Read it once as the recipient, fix anything that is not true, then copy it into your mail app.
Worth asking for
- • Three subject line options to choose from.
- • A version in another language if the recipient prefers it.
- • A one-line summary at the top for a long email.
Subject lines and length
The subject line decides whether the email is opened now, later or never. The ones that work say what the email is about in plain words: "Invoice 1042 is 14 days overdue" beats "Quick question". Ask the AI for three options and pick the most specific one. For a reply, keep the original subject so the thread stays together.
Most work emails do their job in 50 to 150 words. Put the ask or the answer in the first two sentences, give the context after it, and end with the next step. If a draft runs long, ask the chat to cut it in half; it keeps the point and drops the padding. If you need a longer message, such as a report or an announcement, the AI writer page covers that kind of text.
Tone is the other lever. The same request can be friendly, neutral or firm, and the right one depends on what has happened so far. A first request is friendly; the third follow-up can be firm. Tell the chat which it is, or ask for two versions side by side. To change the tone of an email you wrote yourself, paste it into the AI rewriter.
How fast do the free models write an email?
We sent one request, polite follow-up on an unpaid invoice, to each free model on 9 October 2026. GPT-5.6 Luna and Grok 4.5 tied on the full answer, Claude Haiku 4.5 wrote the longest answer. Every model wrote a usable email; pick by the voice you like.
| Model | First words after | Full answer after | Length |
|---|---|---|---|
| 01Claude Haiku 4.5 | 10 s | 12 s | 123 words |
| 02GPT-5.6 Luna | 9 s | 9 s | 66 words |
| 03Grok 4.5 | 7 s | 9 s | 85 words |
AI email generator FAQ
Answers to what people ask most about writing emails with AI.
Yes. The chat on this page writes emails for free with GPT-5.6 Luna, Claude Haiku 4.5 or Grok 4.5, and it works without an account. Guests have a daily limit. A free account adds energy to start, and more you can claim each day, for the larger models.
Yes, and so can Claude and Grok. Any of these models can write, reply to and rewrite emails. On N33 you can try the same email with more than one model and keep the version that sounds most like you.
For everyday emails the free models are enough. Claude models tend to write in a natural, even tone, which suits sensitive emails; GPT models are good at tight, structured messages. The best check is to ask two models for the same email and compare.
Say who the email is for, what you need from them and the facts that matter, then ask for a draft with a subject line. Read it, ask for changes, and copy the final version into your email app. The chat does not send email for you.
Nothing on the free models. With an account, larger models use energy per message: a little for models like Claude Sonnet 5 or GPT-5.6 Terra, more for the largest ones.
Yes. Paste the email into the chat and say what you want to answer. It works as an AI reply generator: the reply follows the thread's tone, and you can ask for a shorter or more formal version.
Treat it like any online service. Remove passwords, account numbers and anything confidential before you paste, or replace them with placeholders and fill them in after.
