Does your email reach the inbox?

Order confirmations in the spam folder and newsletters that never arrive almost always share one cause: a half-finished DNS record. This check reads the public mail records of your domain – SPF including the notorious limit of ten DNS lookups, DKIM, DMARC, MX, MTA-STS, TLS reporting and DNSSEC – and tells you how to fix every red finding.

The domain you send email from – without https:// and without a path. An email address works too; we take the part after the @.

DKIM selectors cannot be listed via DNS. We probe ten common ones – if you know yours, we check it specifically as well.

The check queries public DNS records of the given domain via Cloudflare's resolver (SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI) and fetches the public MTA-STS policy file if present. No email is sent or read. Results are cached for up to 30 minutes. The result is a technical snapshot without warranty.
