SPF checker
SPF Checker
Look up a domain’s SPF TXT record and understand the mechanisms it uses to identify matching mail senders.
Free DNS lookup
Check a domain
Enter a domain, website URL, or email address. We’ll find and parse its published SPF record.
What we check
The checker requests TXT records for the domain and identifies the record beginning with v=spf1.
What we parse
It shows common mechanisms, qualifiers, redirect information, and the final all policy without recursively evaluating them.
What it does not prove
An SPF record does not guarantee delivery, prevent all spoofing, or prove that a website is secure.
