SPF, DKIM and DMARC monitoring is live
A missing SPF or DMARC record doesn’t bounce back to anyone. Mail just starts landing in spam, or getting rejected outright, weeks before anyone notices. It’s now checked the same way the rest of your DNS is.
No signup. Real results in about four seconds.
SPF and DMARC are read as part of the same daily DNS check that already covers A, MX and NS records — no new setup, nothing to enable on an existing domain. If either one disappears while the rest of a domain’s DNS stays put, it’s flagged with the same urgency as a vanished MX record, not lumped into a generic “DNS changed” notice.
DKIM is checked too, but only as a best-effort signal against a handful of common selector names — there’s no standard way to discover which selector a domain actually uses, so a DKIM record not found under those names is never reported as missing, only shown as inconclusive on the free checker.
