MailSnitch - Who spams you?
(the very first version - help us grow - FREE FOREVER)
━━━━━━━━━━━━━━━━━━━━━━━
Trust is good Tagging is better.
Use automated email tagging to take control
and know who’s behind unwanted spam.
━━━━━━━━━━━━━━━━━━━━━━━
PROBLEM:
You get spammed, but don’t know who’s behind it.
Your email address was sold – but by whom?
SOLUTION:
With MailSnitch, every email you use is uniquely tagged.
Now you can track *exactly* where you entered it — and who sold it.
Example:
name@gmail.com name+google001@gmail.com
If you get spam to this address Snitched.
No more guessing. No more spam surprises.
━━━━━━━━━━━━━━━━━━━━━━━
WHAT IS EMAIL TAGGING
━━━━━━━━━━━━━━━━━━━━━━━
You simply add +anything before the @ in your email.
Example:
name@gmail.com → 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

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