Email Health Checker
One lookup, a full deliverability picture. We check MX, SPF and DMARC together and grade the domain A–F with a clear pass/fail list — so you know in seconds whether a domain is set up to actually reach the inbox.
MX, SPF and DMARC — one grade.
The health checker runs all three core deliverability records at once and grades the domain A–F, with a clear pass/fail list so you know exactly what to fix.
- 01
Can it receive mail?
We confirm MX records exist — the baseline for any working email domain.
- 02
Is sending authenticated?
We check SPF is present and ends in a strict all policy, the foundation receivers use to trust your mail.
- 03
Is spoofing stopped?
We check DMARC exists and actually enforces (not p=none), then roll it all into a single A–F grade.
