Why it matters
Google, Yahoo, and Microsoft reject bulk senders without DMARC — and attackers exploit every domain that has not enforced it.
Since 2024, the major inbox providers reject bulk senders that fail authentication. No policy means your invoices, receipts, and campaigns quietly vanish into spam.
Attackers impersonate your domain to scam your customers. Enforcement tells inbox providers to reject the fakes outright — we catch every attempt as it happens.
Authenticated domains earn reputation. Watch placement climb as your records move to enforced.
Discover every service sending as your domain — including the ones nobody told you about.
Raw reports are unreadable. Ours arrive as plain-English fixes you can act on immediately.
Fix ready: add one CNAME at k1._domainkey to align Mailchimp DKIM.
How it works
Three steps. One DNS record. No consultants, no migrations, no downtime.
Compare
Most solutions were built a decade ago — bloated, confusing, and priced for enterprises. Here is the honest side-by-side.
Loved by teams
“We moved to a reject policy in three weeks without losing a single legitimate email. The plain-English insights alone are worth it.”
“Google started bouncing our invoices overnight. Mailtest.ai showed us the exact broken record in minutes — not the weeks our old provider quoted.”
“Finally a DMARC tool the whole team understands. No more XML dumps, no more guessing, no more fire drills.”

Your mail server can fail at four different layers — connection, authentication, port, and TLS. SMTP testing checks each one directly, so you know exactly what's broken before your users do.

Everything teams usually ask before securing their domain.
No. You start in monitoring mode (p=none), which changes nothing about delivery. We watch your reports, identify every legitimate sender, and only recommend enforcing once your mail streams are clean. You stay in control of every change.
Under five minutes for most teams. Add your domain, paste the single DNS record we generate, and reports start flowing within 24–48 hours. Works with Cloudflare, GoDaddy, Route 53, and every major DNS provider.
Never. Mailtest.ai sits on top of your existing stack — Google Workspace, Microsoft 365, Mailchimp, SendGrid, or all of them at once. If a service sends email as you, we monitor it.
A record alone is a security camera nobody watches. DMARC reports arrive as raw XML — thousands of unreadable lines. We parse every report, surface the real threats, and tell you exactly what to fix and when it is safe to enforce.
No. DMARC reports contain metadata only — who sent, from where, and whether authentication passed. We never see message bodies, subject lines, or recipient data.
