โ Trust is good โ Tagging is better.
Use automated email tagging to take control
and know whoโs behind unwanted spam.
โโโโโโโโโโโโโโโโโโโโโโโ
๐ซ PROBLEM:
You get spammed, but donโt know whoโs behind it.
Your email address was sold โ but by whom?
๐ฏ SOLUTION:
With MailSnitch, every email you use is uniquely tagged.
Now you can track *exactly* where you entered it โ and who sold it.
๐ฌ Example:
name@gmail.com โ name+google001@gmail.com
If you get spam to this address โ Snitched.
No more guessing. No more spam surprises.
โโโโโโโโโโโโโโโโโโโโโโโ
๐ WHAT IS EMAIL TAGGING?
โโโโโโโโโโโโโโโโโโโโโโโ
You simply add +anything before the @ in your email.
Example:
name@gmail.com โ name+shop123@gmail.com
All emails still arrive in your inbox,
but now YOU know exactly where you used them.
We call them: Snitch-Mails ๐

๐ธ๏ธ CATCH-ALL MODE (NEW)
โโโโโโโโโโโโโโโโโโโโโโโ
You have your own domain
and want extra control?
Example:
โ Domain: yourdomain.com
โ Generated: shop001@yourdomain.com
Everything before the @
is created automatically.
Unlike Plus-Addressing
(e.g. name+shop001@gmail.com),
thereโs no "+" involved โ
just clean email prefixes.
๐ Why use it?
Some websites or data brokers
strip out anything after "+".
Catch-All emails avoid that โ
your tags stay untouched.
