# An address per signup and who leaked it

Give every site its own address, then see which one starts getting spam.

Address Receiving

shop@ acme.com spam

news@ acme.com spam

flights@ acme.com spam

Switch one off and new mail stops. What already arrived stays.

How it works

## Running in three steps.

1. 01
   
   Invent an address
   
   Type shop@yours.com into the signup form. Nothing to set up first.
2. 02
   
   Watch what arrives
   
   Settings, Addresses lists every address and when it last received.
3. 03
   
   Close the leak
   
   Switch that address off, or block the sender outright.

What it runs on

## The parts doing the work.

Nothing here is a separate product. Each one is a piece of the mailbox you already have.

Catch-all addresses

Every address on the domain receives, including ones that have never been created. One switch closes it.

hello@ yourdomain.com delivered

billing@ yourdomain.com delivered

careers@ yourdomain.com delivered

anything-at-all@ yourdomain.com delivered

oct-2026-signup@ yourdomain.com delivered

Merged inboxes

Read every address in one stream, or narrow to the two or three you actually work out of.

hello@acme.com

me@acme.dev

support@acme.io

one inbox

Block a sender or a domain

One address, or everything from a domain, stopped before it reaches you.

Tracking pixels come out before a message is drawn, and remote images load only when you allow them.
