Email Deliverability Test

Every check this tool runs uses Google's public DNS resolver to pull live records for your domain — no simulation, no cached data. The score is a weighted sum of five authentication and reputation signals, each worth up to 20 points.

• SPFLooks up the v=spf1 TXT record and scores based on the all-mechanism (-all strongest, +all dangerous).
• DKIMProbes nine common selectors (default, google, selector1/2, dkim, mail, k1, s1, s2) for a public key or CNAME. Custom selectors won't be detected.
• DMARCReads _dmarc.yourdomain and scores the policy — p=reject strongest, p=none weakest.
• MXCounts MX records; 2+ means redundancy and signals a real mailbox setup.
• ReputationBonus signals — A record resolution, BIMI configuration, and MTA-STS enforcement all contribute.

What the Score Means

80–100 — your authentication is well configured and most mailboxes will trust your mail. 60–79 — decent but missing pieces; warnings below are worth fixing. 40–59 — significant gaps, expect spam folder delivery. Below 40 — critical issues; mail is likely being rejected outright.
