Free SPF Record Checker

Paste your domain to see if your SPF record is valid, correctly enforced, and under the 10-lookup limit — plus DKIM, DMARC, and blacklist status while we're at it.

Your domain — the website address, not an email address (gmail.com, outlook.com, etc. are already set up correctly)

We only read public DNS — never your inbox. Nothing is stored unless you explicitly ask us to email you a copy.

TipSending marketing or transactional email from a subdomain, like mail.yourdomain.com or news.yourdomain.com? Check that separately — it needs its own SPF, DKIM, and DMARC, and a clean result above doesn't cover it.

Over the lookup limit? See exactly what's using them up.
