Email Tag Autofill — Max

Sarah signed up for an online fitness app using sarah+FITPRO@gmail.com. Three months later, she started receiving sketchy weight-loss spam emails - but they were all addressed to sarah+FITPRO@gmail.com.
She immediately knew:
1. FitPro leaked or sold her email - no other company
had that specific address
2. She could block it surgically - created a Gmail
filter to auto-delete anything sent to that tag
3. She reported the breach - contacted FitPro with proof
they compromised her data
4. Her main email stayed clean - the spam never touched
her real address

Without email tagging, Sarah would have had no idea which of the 50+ services she uses leaked her email. She might have blamed the wrong company, or worse, assumed her email was "just out there" with no way to stop it.

This extension works with any email provider that supports "plus addressing" (also called subaddressing), including:
- Gmail (user@gmail.com)
- Google Workspace
- Outlook / Hotmail
- Yahoo Mail
- iCloud Mail
- ProtonMail
