Enter your domain and we check whether your mail servers appear on public spam blocklists, then audit the DNS behind your email — nameservers, MX records, SPF, DKIM, DMARC and MTA-STS — and explain what any gaps actually mean.

We only read public DNS records and public blocklists. Nothing is stored, and no mail is sent or received.

What we check

Public spam blocklist reputation for your mail server IPs
MX records and the mail servers receiving your email
SPF policy strength and lookup-depth limits
DKIM signing keys across common selectors
DMARC enforcement level and reporting destination
MTA-STS and authoritative nameservers
An overall A–F reputation grade
