DKIM Checker
Check a DKIM selector under selector._domainkey.domain.
Run the check
Enter a public target. Checks are a point-in-time sample; private and internal addresses are blocked.
Why it matters
DKIM signs outgoing mail so recipients can verify messages were not altered.
Plain-English examples
- Check default._domainkey.example.com
Recommended fixes
- Publish the selector from your mail provider
- Rotate weak or missing DKIM keys
Understanding the result
Use findings as a starting point, confirm the intended configuration with your provider, and retest after a change. A successful check does not guarantee security, delivery, uptime or search rankings. Results depend on public DNS and what the server exposes at the time of the check.
