SPF Checker
Enter your domain to verify your SPF record in real time. We read your live DNS and tell you exactly what to fix.
What is SPF?
SPF (Sender Policy Framework) is a DNS TXT record that lists which servers are allowed to send email for your domain. Receiving servers use it to detect forged senders. A missing or broken SPF record is one of the most common reasons legitimate mail lands in spam.
How does this checker work?
We query your domain's live DNS TXT records directly (no third-party API) and look for a valid v=spf1 record. If it's missing or weak, we show a recommended record you can copy into your DNS provider.
What should my SPF record look like?
It starts with v=spf1, lists your senders via include: or ip4:/ip6: mechanisms, and ends with an ~all (soft fail) or -all (hard fail) qualifier. Keep it under 10 DNS lookups to stay valid.
