How it works
Toxic Domain Checker
Flag domains associated with abuse and complaints. 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 Run check.
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.
