Tool

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.

What this tool is – and what it is not

The check produces an automated technical snapshot – results can be incomplete or wrong and come without any warranty. They are not legal, tax or other professional advice. Decisions you make based on the results are your own responsibility. Liability for this free tool is limited to the extent permitted by law – details in the legal notice.

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.
