Mail DNS Records

MX, SPF & DMARC Record Checker

Inspect MX, SPF and direct _dmarc TXT records, including missing or duplicate records.

The percentage counts MX, one SPF and one DMARC record. It is not a security or delivery score. DKIM, SPF expansion, organizational-domain fallback and message alignment are not tested. A null MX (0 .) means the domain does not accept email.

Why are my emails going to spam? Four checks

Record presence cannot guarantee delivery. Use the sending domain and the actual outbound mail server.

  1. 1. Inspect mail DNS records

    Check MX, SPF and the direct DMARC record. Review missing or duplicate entries using your sending provider's instructions.

    Check MX, SPF and DMARC →
  2. 2. Read a real message's authentication results

    Inspect SPF, DKIM and DMARC in the Authentication-Results header of a received test message. This page does not test DKIM or message alignment. You do not need to upload the email here.

  3. 3. Check the sending IP

    Find the outbound IP in message headers or ask your mail provider. Your website IP and MX host may be different. An unavailable DNSBL result is unknown, not clean.

  4. 4. Recheck after changes

    DNS caches and TTL can delay visible changes. Recheck the records; if delivery still fails, review the receiving server's error code with your mail provider.
