Free AI Email Reply & Response Generator
Need help writing emails? Paste the email you received (or describe the one you need to write), pick a tone, and get a ready-to-send reply in seconds. Free, no sign-up, any language.
On a Mac? Skip the copy-paste.
MailReply lives in your menu bar: select any email, press ⌃Space, done. It learns your style, too.
Help writing emails, in three steps
1. Paste the email you received, or describe the email you need. 2. Pick a tone: professional for work, friendly for warm threads, direct when brevity matters. 3. Edit the result if you like, copy, send. The reply always comes back in the language of the original email.
This professional email writer is powered by the same engine as the MailReply app for Mac, where the whole flow is a single keystroke in any mail app: Apple Mail, Gmail, Outlook and the rest.
Email reply examples, by situation
A few typical emails and the kind of response the generator writes for them. Paste your own above to get one tailored to your thread.
Declining a meeting politely
"Can we jump on a call Thursday at 3pm to go over the Q4 plan?"
Hi Sarah, Thanks for reaching out. Thursday at 3pm doesn't work for me, unfortunately. Could we do Friday morning instead, or would a short written summary of the Q4 plan help in the meantime? Best, Tom
Following up on an unpaid invoice
You describe it: "polite reminder, invoice 42 was due last week"
Hi Mark, I hope all is well. A quick reminder that invoice #42 was due last Friday. Could you let me know when we can expect the payment? Happy to resend the invoice if useful. Thanks, Anna
Answering a customer complaint
"My order arrived damaged and nobody answered my last message."
Hi Laura, I'm sorry your order arrived damaged, and that we were slow to reply. I've arranged a replacement that ships today, and you'll get the tracking number within a few hours. No need to send the damaged item back. Kind regards, Customer Care
Saying yes to a request, briefly (Direct tone)
"Could you send me the final deck before Monday?"
Sure, you'll have it by Friday afternoon.
How to reply to an email professionally
The generator follows the same rules a careful writer would. If you prefer to write the reply yourself, these are the ones that matter most:
- Answer the actual question first. Put the yes, the no or the date in the first two lines; context comes after.
- Match the sender's register. A two-line message deserves a short reply; a formal request deserves a formal one.
- Make the next step obvious. End with what happens now: a date, a decision, an attachment, a question.
- Keep it skimmable. Short paragraphs, one topic per email, no walls of text.
- Reread before sending. Names, numbers and dates are where replies go wrong.
For format, sign-offs and more templates, read our guide on how to write a professional email. If you're stuck on a tricky message and just need a starting point, see help me write an email: a practical guide.
Whatever the generator writes, you're in control: the reply lands in an editable box, nothing is sent for you, and you decide what goes out.
Questions, answered
Is this email response generator really free?
Yes: 5 AI replies per day, no sign-up, no card. For unlimited one-keystroke replies on your Mac, there's the MailReply app.
Can it help me write an email from scratch?
Yes. Describe what you need ("write a polite follow-up about the unpaid invoice") and the AI drafts it: it works both as a reply generator and as an email writer.
What languages does it support?
All of them: the reply comes back in the same language as the email you paste.
Is my email stored?
No. The text is used only to generate your reply, then discarded. Nothing is saved or reused.
Does it work for Gmail and Outlook replies?
Yes. Copy the email from Gmail, Outlook, Apple Mail or any other client, paste it here, then copy the reply back. On a Mac, the MailReply app does it in place with one keystroke (see AI email replies in Outlook).
Will the reply sound like me?
Pick the tone that fits and edit the result freely: nothing is ever sent for you. The Mac app goes further and learns your writing style over time.
How long should an email reply be?
As short as it can be while still answering everything that was asked. Most work replies fit in three to six sentences; use the Direct tone when one line is enough.
