Enter your domain. We test the signals spam filters weigh, SPF, DKIM, DMARC, TLS, MX, reverse DNS and IP blocklists, and score how likely your email is to land in the spam folder. No signup, no email required.
This check is a snapshot. Inboxproof Pro re-checks your domain daily, tracks your score over time, and alerts you the moment a record or your IP reputation breaks.
