13RT Mail
13RT
Email that knows<br>who sold you out.
One address, infinite disguises. Give every company its own version of<br>your email — and the moment one of them leaks it, sells it, or gets<br>breached, you'll know exactly who it was.

How it works
Claim your handle
you@13rt.com is yours — and so is every address that ends in<br>.you@13rt.com , automatically, forever. Nothing to set up per alias.
Never give out your real address again
Signing up somewhere? Type theirname.you@13rt.com into the form.<br>It lands in the same inbox — permanently tagged with who you gave it to.
Catch the betrayal
Their first email — usually the opt-in — arrives asking one question:<br>is this who you gave the address to? One tap confirms them as the<br>rightful sender, or marks the mail as a leak if a stranger got there<br>first. Once you've confirmed the intended sender, mail from anyone<br>else arrives wearing a red flag: this address leaked.<br>Evidence, not suspicion.
Then make it stop
🗡 The kill switch
Done with a leaked alias? Kill it. Every message it ever received is<br>deleted, and all future mail to it is buried before it touches your<br>inbox — with a counter showing how much spam died at the door.
👁 Know when you're read
Mail you send reports back: how many times it was opened, when, and<br>whether it's being opened on devices you didn't send it to.
📥 A real inbox
Read, reply, archive, attachments — a full mail client. Reply<br>as any alias, so companies never learn your real address<br>even when you write back.
