Is your domain protected against email spoofing?
Enter a domain you own or manage. We read its public DNS records and grade how well it resists forged email and how safely mail reaches it, with plain-language fixes.
Included in the monthly plan
What it does
SPF, DKIM and DMARC
Which servers may send mail as your domain, how messages are signed and what receivers do with forged ones.
Transport security
MTA-STS, TLS-RPT and DNSSEC: whether other servers must use encrypted, verified delivery to you.
Passive and safe
Only public DNS records and one public web page are read. No port scans, no connections to mail servers.
Domain email security
