Every alias service hides your real address. Don't SPAM Me also tells you which company leaked it. It puts unlimited catch-all aliases on a domain you own. Type any address into a signup form and it starts working with the first email. When an alias gets mail from a sender other than the company you gave it to, you get an alert naming that sender, and the company goes on a Data Sellers list. Disable an alias and it rejects mail with a hard bounce (SMTP 550), so senders stop mailing it.

I built this because I wanted a clear answer to "who sold my email address", not a better spam folder. Most alias services hide your address, which helps. But when spam starts arriving, you still have to work out where it came from. Here, every alias keeps its own spam count, and when a sender that isn't the original signup company mails it, you get told by name. Two choices were deliberate. Aliases only work on a domain you own, because addresses on my domain would stop working the day you left. And disabling an alias bounces mail instead of silently dropping it, because a bounce makes the sender's own platform stop mailing that address. Not there yet: replying from an alias, a browser extension, PGP and open source. Happy to answer anything.
