Is there an AI for writing my emails?

Is there a free AI email generator?

Yes, and for everyday email free is enough. Since January 2026, Gmail's Help me write drafts from a prompt at no cost on personal accounts in the US, in eight languages; outside the US it comes with a paid Google plan. Every general chatbot in the list below also writes emails on its free tier: you paste in the facts, it hands back a draft, you paste that into your mail app.

What free holds back is the part that saves real time. The grammar-and-tone assistant in the list caps its free plan at 100 AI prompts a month. Outlook's assistant needs a paid Microsoft 365 plan on personal accounts. The mail client that learns your tone from sent mail has no free plan at all. And on the no-signup generator sites you are pasting your email, names and all, into a server you know nothing about: fine for a thank-you note, not for a contract.

AI email assistant or email generator: which one you need

A generator writes when you ask: you describe the email, it drafts, you copy. An AI email assistant lives in the inbox. It reads the thread you are answering, can have replies drafted before you open them, and picks up your tone from mail you already sent. Its drafts need less editing because it already has the context.

You pay for that in access and in money. An assistant reads your whole mailbox, so check what it stores and whether it trains on your mail before you connect a work account. The ones that write in your voice cost about $25 to $40 a month. If most of your email is replies, answering my emails covers the reply-drafting tools; for what the built-in assistants do beyond writing, see Gmail and Outlook.

Rewrite an email you already wrote

This is often the better job to give it. You write the rough version with the facts, the names and the ask; the AI fixes the order, the length and the tone. Because the facts are yours, there is little to check. Drafting from nothing is where a model fills gaps with plausible details: a deadline you never set, an apology you did not owe, a call you never offered.

Say what must not change: keep the dates, no new promises, under 120 words. The big mail apps now have a rewrite option with tone presets such as professional or concise, which is enough for a quick pass. Then read the result against your original for anything it added.

Professional email writer: sounding professional, not generated

Ask an AI to make an email sound professional and it usually makes it longer and stiffer: the hope-this-finds-you-well opener, a hedge in every sentence, a three-line sign-off. Professional mostly means short, specific and polite. Tell it who the reader is (a client you have emailed for a year, a recruiter you have never met), the one thing you need from them, and paste one email you sent before as a style sample. More on getting it to sound like you.

Then cut, starting with the opening and closing lines, which is where the filler collects. If the email is about a person rather than a task, such as thanks, praise, bad news or feedback, write it yourself and let the AI fix only the typos. That is where readers mark you down for it.

writing my emails: quick answers

Can AI write an email for me?

Yes, in seconds. Give it three things: who the email is for, what you want them to do, and the facts it cannot guess, like dates, amounts and names. Anything you leave out it will either pad or invent, so read the draft for promises you did not make before you hit send.

Can people tell an email is AI-generated?

Often, and it costs more than you would expect. In a 2025 study of 1,100 professionals, 83% saw a manager as sincere when a message had little AI help, but only 40% to 52% did when it had a lot, even though most still rated those messages professional. Routine notices were fine; praise, congratulations and feedback were where it hurt.

Can Gmail write my emails for me?

Yes. Help me write sits in the compose window on the web, Android and iOS, and drafts from a one-line prompt. Since January 2026 it is free on personal Gmail accounts in the US; elsewhere it needs a paid Google AI plan or an eligible Workspace plan. Our Gmail page covers what it does in the rest of the inbox.

Is there an AI email assistant for Outlook?

Yes, Microsoft's own, in Outlook on Windows, Mac, the web and mobile. It drafts from a prompt, changes tone and length, and on iPhone and Android can coach a draft you wrote yourself. Personal accounts get it with a Microsoft 365 subscription from $9.99 a month; work accounts depend on what your employer licenses. Details on our Outlook page.

What is the best AI for writing emails?

The one already in the mail app you use, because it sees the thread and you skip the copy and paste. If yours has none, or you want drafts in your own voice, the paid mail client in the list does that for $25 to $40 a month depending on plan and billing. For an occasional email, any free chatbot tier is enough.
