Let’s write an email!
Type a few lines about what you need to say, or paste your notes. Replying to someone? Open Details above and paste their email.
Say what the email has to do, in a sentence, and press Generate email. This free AI email writer returns a subject line with two alternatives, a greeting, the body and a sign-off, already in position. Paste an email you received and it writes the reply, answering each point in the order it was asked. A chatbot gives you prose; an email needs a shape.

Three steps, and the third one is the one that matters.
Most people arrive at an AI email generator with a sentence, not a specification — “tell the supplier the invoice is wrong and we need it reissued” is enough. Names, dates, prices and links carry through exactly as you typed them.
Sixteen purposes cover the emails people actually send. Eight tones set the register, from concise to formal. Three lengths decide whether the answer is three lines or three paragraphs.
You get a subject line with two alternatives and a body you can edit in place. Six one-tap refinements make it shorter, warmer or more direct without rewriting the brief.
A subject line, a greeting, the ask, a sign-off. A general chatbot hands you prose and leaves you to cut it into an email.
Paste the message you received and the reply works through its points in order, instead of writing around them.
Formal for an admissions office, concise for a colleague. Change your mind after the draft and it re-registers in one tap.
Sixty-four languages across seventy-three regional variants, or it detects the one your brief was written in.
The purpose, tone and length stay set between emails, so the tenth message of the morning takes as long as the first did to send.
Subject and body are both editable in the page, with a live word count and reading time under them.
You write the situation. The email writer returns a subject line and a body, with every fact from your brief still in place.
Paste the email you received. The reply works through its questions in order instead of writing around them.
Two things people use an email generator for that a template cannot do. Both runs below were made on 30 September 2026 and are printed unedited.
Rewrite this so it sounds professional: hey can u send me the invoice for august asap, we need it for the audit on friday. thx
Hi Maria,
Could you please send me the August invoice at your earliest convenience? Our audit is scheduled for Friday, and we need the document beforehand.
Thank you for your prompt attention.
Best regards,
Sam
Paste your own draft as the brief and say what you want changed: it works as an email rewriter. One thing to check: “asap” became “at your earliest convenience”, which sounds less urgent. Friday still carries the deadline, but if it is urgent, say so. Subject alternatives offered: “August Invoice Needed for Audit” and “Please Provide August Invoice”.
Hi Sam,
Thanks for the proposal. Two quick questions: could we do a call on Thursday at 3pm to go through it, and is there any flexibility on the budget if we sign for 12 months instead of 6?
Best,
Daniel
Your brief: Say yes to the call on Thursday at 3pm, but the budget question needs our finance lead, so I will get back on that by Monday.
Hi Daniel,
I can confirm the call on Thursday at 3 pm to review the proposal. Regarding the budget flexibility for a 12-month commitment, I’ll need to consult our finance lead and will get back to you with a definitive answer by Monday.
Please let me know if there’s anything you’d like to add to the agenda for Thursday.
Best regards,
Sam
Both of Daniel’s questions are answered, in his order, and the Monday date survived. Subject alternatives offered: “Thursday call scheduled” and “Re: Thursday meeting and budget”. One thing to watch: in an earlier run of the same brief, the reply added “I’ll send a calendar invite shortly”, which the brief never said. A reply generator can commit you to things, so read for promises you did not make before you press send.
The hardest email to get right is the second one. Here is a sales follow up email sample the tool produced from a brief that said little more than “quote sent Tuesday, no reply”.
Follow up on the quote I sent Tuesday for the 5,000 kraft mailers. No reply yet. Their launch is 12 September so the timing is tight. Offer to jump on a 10-minute call. Do not sound pushy.
Hi Rachel,
Just wanted to touch base about the quote I sent on Tuesday for the 5,000 kraft mailers. I know your launch is set for 12 September, so I understand the timing is tight. If it helps, I’m happy to hop on a quick 10‑minute call to go over any questions or details.
Let me know if you’d like to schedule a time that works for you, or feel free to reply with any thoughts you have.
Thanks, Sam Ellery
Note what it did not do: no “just circling back”, no second apology, no guilt. A follow-up works when it gives the other person a cheap way to respond — here, a ten-minute call — and stops.
Formality is not longer words. It is a full salutation, one sentence saying why you are writing, and no throat-clearing before the ask.
Ask the admissions office to confirm whether my transcript, sent by post on 3 August, has been received, and whether anything else is outstanding before the 30 September deadline. Formal.
Hi Dr Helena Marsh, Admissions Office,
Could you let me know if the transcript I mailed on 3 August has arrived? I’d also appreciate a quick heads‑up on any other documents you might still need from me before the 30 September deadline.
Thanks for checking on this. I want to make sure everything’s in order well before the deadline.
Best regards, Sam Ellery
And here is the honest part: the greeting came back as “Hi Dr Helena Marsh, Admissions Office”, because that is exactly what was typed into the recipient field. A formal email wants “Dear Dr Marsh”. That is a two-second fix, and it is the sort of line worth reading for before you send anything a tool wrote.
The purpose changes the shape of the email, not just its wording. A request opens differently from an apology, and a follow-up is not a reminder.
Any everyday email that does not fit a pattern.
Answer a message you were sent, point by point.
Ask for something clearly enough to get a yes or a no.
Chase a quote, a decision or an unanswered message.
A nudge about a date or a task, without nagging.
Say thank you in a way that names what they did.
Own a mistake and say what happens next.
Reach someone who has never heard from you.
Propose, confirm or move a time.
Invite people and tell them what to expect.
Share news with a group in one pass.
Help someone with a problem and close the loop.
Raise a problem firmly and fairly.
Give feedback that can be acted on.
Apply for a role without repeating your CV.
Resign in a way you can stand behind later.
Most tools in this category send you to a separate page for this. It belongs next to the email.
The tool returns three subject lines for this reason — one in place and two alternatives — because the right one depends on the inbox it lands in, and you know that better than a model does.
Most of what makes an email land is restraint. These are the rules the draft is written to, and the ones worth checking before you send.
Keep the part you are answering and cut the rest. A reply dragging twelve messages behind it makes the reader scroll to find out whether anything changed.
If they asked three things, answer the first thing first. Re-ordering their questions to suit your answer reads as evasion even when it is not.
Someone who wrote “Hi Sam” does not want “Dear Mr Ellery” back, and three formal paragraphs deserve more than a one-line reply.
Ask whether every name on the thread needs the answer. If two of them do, move those two to a new message rather than making nine people read it.
A refusal buried under two paragraphs of warm-up is read as a yes until the reader hits it. Lead with the answer, then explain.
A generated reply will happily be firm on your behalf, which is exactly why it is worth rereading an hour later. The tool has no stake in the relationship. You do.
Set them before you write, or change your mind afterwards.
| Control | What it does | Options |
|---|---|---|
| Tone | Sets the register of the whole email, including the greeting and the sign-off. | Professional, Friendly, Concise, Confident, Empathetic, Persuasive, Formal, Casual |
| Length | Decides whether the answer is three lines or three paragraphs. | Short, Standard, Detailed |
| Refine | One tap on the finished draft, without rewriting the brief. | Shorter, Longer, Friendlier, More formal, More direct, More polite |
| Details | Who it is for, how to sign it, and the message you are answering. | Recipient, your name, pasted incoming email |
| Language | Writes in the language you choose, or the one it detects from your brief. | Auto-detect, or 64 languages across 73 regional variants |
Research on AI-written email is not flattering: people told a message was AI-drafted tend to rate the sender as less trustworthy. That is a good argument for using this on the twelve routine emails a day and writing the thirteenth yourself.
Clear the twelve routine messages so there is time for the one that matters.
Write to a lecturer, a landlord or an admissions office without agonising over the wording.
Send the message you have been putting off — a complaint, a refund, a difficult thank-you.
A tool that turns a short description of a situation into a complete email. Unlike a general chatbot, an email AI writer returns the parts an email actually needs — a subject line, a greeting, the ask and a sign-off — already in position, with controls for purpose, tone and length.
Yes. You can write emails without an account: briefs of up to 400 words as a guest, 1,000 with a free account and 3,000 on Pro, which also removes the ads. The limit counts the brief and any email you paste in, never the draft written back. All 16 purposes, all eight tones, Refine and the downloads are on every plan.
Yes. It works straight away, and your drafts are saved in your own browser so you can come back to them. An account raises the limits and lets your drafts follow you between devices.
Tell it the outcome you want rather than the words you would use. “Get them to confirm Friday without sounding pushy” produces a better draft than a list of adjectives. Include the facts that must appear — dates, amounts, names — and leave the phrasing to the tool.
Yes. Choose the Reply purpose and paste the message into the details panel. The draft answers the sender’s points in the order they asked them rather than writing around them.
Yes. Paste your draft into the brief and say what you want, for example “Rewrite this so it sounds professional”, and pick the purpose and tone. It returns a new subject line and body with your facts kept. Check the urgency afterwards: in our test, “asap” came back as “at your earliest convenience”. To change only the tone of an email without redrafting it, the tone changer is the better tool.
Put the point in the first sentence, then the reason. Use a subject line that says what the email is about, one request per email, a date instead of “asap”, and a greeting and sign-off that match how the other person wrote to you. The section above on professional email conventions covers the rest.
Yes. Every draft comes with a subject line and two alternatives you can swap in with one click, plus a live character count, because phone inboxes cut subjects at around 35 to 40 characters.
A chatbot hands you prose in a chat window. A dedicated email AI writer hands you a subject line with alternatives, an editable body, a live word count, and one-tap changes like “more direct” or “shorter” — and it keeps the purpose, tone and length you set instead of you retyping them each time.
Use a full salutation, say why you are writing in the first sentence, put the request in its own line, and close with a conventional sign-off. Formality is structure, not longer words. Choose the Formal tone and the draft follows that shape — then check the greeting, which is the line most worth fixing by hand.
Say what the email is about rather than hinting at it, put the identifying words in the first 35 to 40 characters because phones cut it there, and leave the subject alone when you are replying inside an existing thread. The tool shows a live character count and offers two alternatives.
Follow-up handles chasing a quote or a decision, and Introduction / outreach handles a first approach. Both work best when the brief says what the other person gets out of replying. Sending the same generated email to hundreds of people is a different activity, and not one this tool is built for.
Spam filters score sending reputation, links and formatting far more heavily than phrasing, so an ordinary one-to-one email is not at risk. Mass identical outreach is a different matter, which is a good reason not to send one generated email to five hundred addresses.
It depends on the email. For routine factual messages nobody minds and nobody notices. For anything where the point is personal effort — condolences, a real apology, thanking someone properly — studies suggest recipients who learn a message was AI-written trust the sender less. Use it for the routine ones.
Yes, in 64 languages across 73 regional variants, or let it detect the language of your brief. Bear in mind that formality works differently in different languages — a German business email expects the formal register, and a literal translation of a casual English opening can read as rude.
Closer than a general chatbot, because tone, length and purpose are set explicitly — but not exactly. The draft is meant to be edited, and changing two or three words is usually the difference between an email that sounds like a template and one that sounds like you.
The brief and any pasted email are sent in order to write the draft, and are not stored as text afterwards. Drafts are kept in your own browser. See the privacy policy for the detail.
Every tool here runs on the same AI powered writing assistant, so the tone you choose for an email behaves the same way in the paraphraser or the summarizer. One plan covers all of them, including the ones we have not built yet.
Each page opens the writer with that purpose already selected, shows a real draft the tool returned from a one-line brief, and explains what that kind of email has to do. The purpose menu above the brief covers all sixteen.
