Signups, forms and downloads

# Hand out addresses you can throw away

Every form wants an address. Give each one its own, see which starts getting spam, and switch that one off without touching the rest.

Soon. When the ring closes the mailbox is gone. It never touches your own mail.

Where it starts

## What this looks like today.

One address does everything

The same address sits on every form you have filled in since your first account.

Spam arrives with no trail

When it starts, nothing in the message tells you which site handed your address on.

Some signups last five minutes

A download link, a code to paste, a wifi login: you need an address once and never again.

How it works

## Running in four steps.

1. 01
   
   Add your domain
   
   A new domain arrives with catch-all on, so every address on it receives from the start.
2. 02
   
   Invent an address in the form
   
   Type shop@yours.com straight into the signup form, and the address exists when the first mail lands.
3. 03
   
   Watch Settings, Addresses
   
   Every address you have used is listed there with the date it last received something.
4. 04
   
   Switch off the one that leaked
   
   Turn that address off, or block the sender outright, and new mail stops while what arrived stays.

What it runs on

## The parts doing the work.

The parts this runs on: catch-all delivery, replies from the address that received, tracking pixels stripped, and the blocking and spam filtering for the rest.

Temporary addresses

A free inbox that takes real mail for an hour, then closes, so a signup cannot follow you.

trial-signup@example.com 60 min

extend it an hour at a time, up to a day

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

Send as any alias

Reply from the exact address the mail arrived on.

to billing@acme.com

from billing@acme.com

Phishing & spam filtering

Mail the sending domain itself disowns lands in Spam rather than the inbox.

receipts@ stripe.com

SPF DKIM DMARC

Block a sender or a domain

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

deals@spammy.io blocked sender

anyone@spammy.io blocked domain

hr@recruit.co language filter

ci@acme.dev your rule → archive

Tracking pixels stripped

The invisible image that tells a sender you opened their mail is gone before you see the message.

tracking pixel stripped

hidden preheader stripped

remote image stripped

0 left to phone home

In practice

## Every piece, walked through.

Each page below is a single run through: an address per site, addresses you never created, and reading with the pixels out.

A mailbox that expires

Soon

Take an address for an hour, read what arrives, and let it expire.

q7k2m9@ pooled domain 58:12

Your verification code 09:41

An address per signup

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

shop@ acme.com

news@ acme.com

Any address you invent

Every address on your domain arrives, including the ones you never created.

Sign-up form shop@acme.com

shop@acme.com Delivered

Read without being tracked

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

Questions

## Asked before signing up.

Do I have to create each address before I use it?

No. Every address on your domain receives from the day the domain is added, including ones you never created, up to 500 per domain. The row in Settings, Addresses appears when the message lands.

Can an address expire on its own?

On your own domain, no: a catch-all address lasts as long as the domain does, and you switch it off yourself. For a signup you never want to hear from again, the free temporary email tool gives you an address that closes on its own after an hour.

Can I reply from one of these addresses?

Yes. A reply leaves from the exact address the mail arrived on, so a message sent to shop@yours.com is answered by shop@yours.com and the site never sees another address.

Email that outlives

Your domain, an address you invent for each signup, and nothing reporting back when you read. Change provider later and the addresses come with the domain.

Your product gets the mail

Every ticket, record or customer can have its own address. Mail sent there reaches your endpoint as a signed event, and your code answers as that address.

Ticket 8123 ticket-8123@ in.yourapp.com
