What does the domain checker look at?
Your domain’s MX, SPF, DKIM and DMARC records, a custom tracking domain, and whether the domain’s own mail servers appear on the PSBL or DroneBL blocklists, which allow free commercial lookups. Spamhaus DBL, SURBL and URIBL need a paid licence for a commercial tool, so they’re only checked when a licence is set up; otherwise check them on each list’s own site.
Why do SPF, DKIM and DMARC matter?
Since 2024, Gmail and Yahoo require senders to authenticate their email. Without these records, even good email is more likely to land in spam.
What if a check says unknown?
We couldn’t get an answer from DNS or a blocklist at that moment. We never show a pass for something we couldn’t check, so try again shortly.
Do I need an account?
No. The domain checker is free and works without signing up.
