SPF lookup
SPF record check for domains you manage
Sender Policy Framework (SPF) publishes which mail servers may send for your domain. This free SPF lookup fetches TXT records, finds v=spf1, lists mechanisms (include, ip4, a, mx, all, and more), and gives basic guidance (for example a missing or soft ~all / hard -all).
Looking for a lighter alternative to a full MXToolbox-style suite? Start here for a focused SPF record check, then pair with DKIM record lookup and DMARC policy lookup for a fuller mail-auth picture. Also see MX lookup when you need mail exchangers.
Frequently asked questions
What is an SPF record check?
An SPF record check (or SPF lookup) reads the domain’s TXT record that starts with v=spf1 and shows which hosts are allowed to send mail. Receivers use that policy when evaluating inbound messages.
How is this different from MXToolbox-style tools?
MXToolbox and similar suites bundle many DNS and blacklist tests in one dashboard. ITCOH’s SPF lookup focuses on a clear SPF parse plus links to DKIM and DMARC — useful when you only need the SPF record check without a heavy multi-tool UI.
Is this private like the PDF tools?
No. DNS lookups require a server-side resolver. Your queried domain name is processed by our lookup API.
What does SPF do?
It lists authorized sending hosts; receivers can fail mail that does not match. Common tags include include:, ip4:/ip6:, and a trailing all mechanism.
Why no SPF found?
The domain may not publish v=spf1, the TXT may live on a different host, or DNS may still be propagating after a change.
Is this a security audit?
Basic guidance only — not a full email deliverability or blacklist audit. Combine with DKIM and DMARC lookups for a broader view.
