The product
Why an app and not a website?
Because LetterForge works directly with the mail app on your computer. Your mailbox stays where it is, and emails go out from your Outlook, Apple Mail or Thunderbird as before.
I already use an ATS.
Then keep it. LetterForge takes care of the emails with candidates and runs next to whatever system you have.
I already use ChatGPT or Copilot.
Then you know the routine: copy the thread in, copy the answer out, fix the names. LetterForge already has the thread, the vacancy and your notes, and the finished email opens in your mail app. Try both on real emails, with 20 free replies a month.
Will it sound like a machine wrote it?
You choose the tone, the greeting and the length. If you like, LetterForge learns your style from emails you have sent yourself. Every email opens in your mail app first, and nothing goes out without your click.
What about the EU AI Act?
LetterForge doesn’t score, rank or filter candidates. It helps you write and keeps track of the conversation. You decide, and you send.
Does LetterForge send emails by itself?
No. The draft opens in your mail app and you press send. LetterForge notices that the email went out and notes it on the candidate.
Privacy & security
What happens to my emails?
Your mailbox stays on your computer, and so do the candidates, emails and notes in LetterForge. For a draft, only that one candidate’s conversation and the details the draft needs go, encrypted, through our server to the AI service. Our server passes them on and does not store them. The request is processed by OpenAI (USA), outside the EU. Requests through the provider’s API are not used for training.

Which mail apps does LetterForge work with?
Apple Mail on the Mac, classic Outlook on Windows and Thunderbird on both. Gmail accounts work once you add them to one of these. LetterForge can’t read the new Outlook yet; a Microsoft 365 account works in classic Outlook.
I use Gmail.
That works, just not in the browser. Add your Gmail or Google Workspace account to Apple Mail, classic Outlook or Thunderbird, which is free and takes a few minutes. LetterForge then reads your emails from there, right on your computer, and needs no access to your Google account.
My IT doesn’t allow installing software.
Please tell us. We note every case and are happy to answer your IT team’s questions directly.
Ask a question →Is there a version for Linux or Chromebook?
Not at the moment, only Mac and Windows. If you need another system, let us know. We keep a list.
Ask a question →Can I use LetterForge on more than one computer?
Yes. Sign in to the app with your account on each computer. Your account lists every signed-in computer and lets you sign any of them out. Candidates and emails are stored on the computer you work on them.
Pricing & billing
What counts as a reply?
Every finished email draft LetterForge writes for you: a reply, a first message or a rejection. A shorter or friendlier version right after a draft doesn’t count again. Emails you write yourself never count.
Is the free plan really free?
Yes. Every feature, no time limit, no credit card. You get 20 replies each calendar month, and on the 1st they start again. Reading emails, the boards, handing emails to your mail app and the export always work.
What happens when my free replies are used up?
Everything else keeps working. From the 1st of next month LetterForge writes again, or you switch to Solo and carry on straight away.
Is the number of candidates limited?
No. Add as many candidates as you like on every plan. Only the replies LetterForge writes are counted.
What happens when the replies of Solo or Team are used up?
Everything else keeps working. Until the 1st of next month you write yourself or start from a template, and the emails are tracked as always. On Team, up to 10 people share 5,000 replies a month. If you regularly need more, write to us.
Can I cancel?
Yes, at any time in your account. Your plan runs until the end of the period you have paid for.
Do I get an invoice?
Yes. Every invoice is in your account as a PDF.
What happens to my data if I cancel?
Nothing. Candidates, notes and emails are on your computer and stay there.
