Mailward watches the DNS behind your clients’ inboxes
A DNS and email-authentication checker that grades domains from A to F, explains bulk-sender requirements, and monitors client domains for configuration drift.
Field notes
Mailward reads DNS records directly rather than waiting for redirected DMARC reports, and its checker covers SPF, DKIM, DMARC, DNSSEC, MTA-STS, TLS-RPT, and BIMI. The page specifically highlights SPF’s ten-lookup limit and DMARC external-destination authorization, then describes daily monitoring through two resolvers with a second-day persistence check. Its displayed agency plan covers 50 domains, three seats, one year of history, and CSV export.
