Email security check

Check SPF, DKIM, DMARC, BIMI, MTA-STS and TLS-RPT for your domain in one test.

Only public DNS records and the published MTA-STS policy are queried. We do not store the domain.

By API or with AI assistants. This check is available in the public API (email/check) and on the MCP server as check_email_security.
