Free · Open source · Zero-data
Set it up once and the senders you ignore stop reaching you — automatically, inside your own Gmail or Outlook account, over the official one-click standard (RFC 8058). It's free and open-source, and nothing about your mail ever leaves your account.
WHY IT'S SAFE
Because nothing ever leaves your account — the architecture is the privacy, not a promise. hover a card for the detail
The script lives in your own Google Apps Script or on your desktop — there is no DontMailMe backend
that could see, store, or sell your mail. Not a privacy policy; an architecture.

Acts on the RFC 8058 List-Unsubscribe-Post header — never clicks links in the body, so it can't be lured to a phishing page.
A single-purpose unsubscribe tool an assistant runs inside your own account — not one that

HOW IT WORKS
No app to install, no account to create, no inbox access to grant a stranger.
We generate a small open-source script for your mail provider. You can read every line — nothing is hidden.
It runs in Google Apps Script (Gmail) or on your desktop (Outlook / Apple Mail). It lives in your cloud, not ours.
The script sends the official one-click unsubscribe for each junk newsletter and tidies your inbox. Set it once.
YOUR PROVIDER

Most unsubscribe tools are free because you are the product, or paid because privacy is sold back to you. DontMailMe is neither.
