How it works
Lookalike Domain Checker
Catch domains one character off Gmail, Yahoo, or your brand. The check runs in your browser. MailShrine Email Sanitization flags invalid syntax, disposable and role-based addresses, and duplicates. It does not probe mailboxes, and it does not send the campaign.
Results appear here after you click Check address.
The full pass — syntax, disposable and role flags, duplicates — is Email Sanitization. You start with 200 credits per month. The send, later, is Email Marketing.
