How to use

How does Gmail alias normalization work?

Gmail ignores periods in user handles and discards text after plus signs (e.g., user+newsletter@gmail.com), routing directly to the root mailbox.

How does normalizing lists improve email deliverability?

Removing malformed syntax and duplicate aliases drastically lowers bounce rates, safeguarding sender domain reputation.

Are my private customer contact lists uploaded anywhere?

Never. All regex parsing and deduplication execute strictly client-side inside your browser sandbox without network transmissions.
