SPF record checker.
SPF tells receivers which servers may send mail for your domain. A missing, duplicated, or too-permissive record sends cold email straight to spam. Enter a domain to look it up and grade it.
Run the check
We look up your TXT record
A server-side DNS query for v=spf1 at your bare domain — no signup, nothing stored.
We grade the policy
Hard-fail vs soft-fail, duplicate records, and a count of DNS-lookup mechanisms against RFC 7208’s limit of 10.
You get a fix list
Each finding says exactly what to change, in the order it matters most.
Other free checks
DMARC checker
Check your DMARC policy, enforcement level, and reporting — the records Gmail and Yahoo now require for bulk senders.
Blacklist checker
Resolve your mail-sending IP and check it against Spamhaus ZEN, SpamCop, and Barracuda — the well-known DNSBLs.
Spam-word checker
Scan a subject line and body for common spam-trigger phrases like "act now" and "100% free" before you send.
