Free email spam test
Send a test. Find the weak spots.
SPF, DKIM & DMARC checker
Test a received email, not just a domain record. Check the sending IP, verified DKIM signatures and alignment with the From domain.
What do the authentication checks mean?
- SPF
- Is the connecting server authorized for the envelope sender?
- DKIM
- Does the signature verify, and which headers does it protect?
- DMARC
- Does a passing SPF or DKIM identity align with the visible From domain?
The guest preview shows authentication and finding counts. Sign in for DNS evidence and fixes. Pasted headers alone cannot verify a live connection or signature.
What can a test reveal?
Example findings. Not a live report.
- DKIM passes. Subject unsigned.
- Ask your provider to include Subject in DKIM signing.
- Button has no destination.
- Add the correct URL before sending.
- Claims need proof.
- Replace an unsupported guarantee with the actual offer.
What does the free test cover?
SPF, DKIM, DMARC, wording, links and MIME structure. The preview shows authentication and finding counts. Sign in for evidence and fixes. Send from your usual campaign tool; this test does not measure Gmail or Outlook folder placement.
