Free SPF and DMARC checker
Check the public email records for your business domain: SPF, DMARC, MX and common DKIM selectors. See what exists and what needs attention, with plain-English results. Works with .ie and other domains. No signup needed; this checks authentication records, not inbox placement.
Somewhere to deliver to (MX)
Proof it’s really you (SPF)
A tamper-proof signature (DKIM)
Your instructions to inboxes (DMARC)
Take the checklist instead, free
All 40 faults the report looks for, each with what it means and what to do about it, ordered by what costs you most. Sent immediately, automatically. One email, not a sequence.
What the SPF checker reads
SPF lists the servers authorised to send for a domain. This checker reads the published record and its ending policy. It does not evaluate every included service or the SPF DNS lookup limit. A published record is a useful starting point, not proof that a message passes SPF.
What the DMARC checker reads
DMARC tells receiving services how to handle messages that fail authentication alignment. A policy of p=none requests monitoring; quarantine or reject asks for stronger handling. Check that legitimate senders authenticate and align before tightening a policy.
What a DKIM lookup can tell you
DKIM uses a public key published under a selector name. We try common selectors. A missing result may mean your provider uses a different name; a found key does not prove your outgoing messages are signed correctly.
Why email can still land in spam
These DNS checks do not send a test email, verify message alignment or measure sender reputation. If records look healthy but delivery is poor, examine a received message’s headers, sending service and recipient feedback. See Google’s email sender guidelines for its requirements.
Check the enquiry path too
An email record problem and a broken contact form need different investigations. Read how to investigate missing contact enquiries, understand email setup for Irish businesses, or try the other free website checks.
