SPF, DKIM and DMARC checker

Check your domain’s SPF, DKIM and DMARC DNS records. Enter a DKIM selector to review email authentication syntax, configuration and policies.

Input

The server queries this domain or URL; results are not stored.

Reads TXT records and checks presence, duplicates and selected syntax errors. It does not recursively evaluate SPF includes, verify message DKIM signatures or guarantee email delivery or spam protection. DKIM needs your email provider’s selector.

Result

No result yet. Fill in the fields and run the tool.

How to use

                        
Enter your email domain (example.com) or a complete URL (https://example.com/page) and, if known, its DKIM selector. The exact hostname from the URL is used, including subdomains such as www: make sure it matches your email domain. Review SPF, DKIM and DMARC separately: a missing record differs from a selector that was not supplied.
