Frequently asked questions about SPF Record Checker
SPF (Sender Policy Framework) is a TXT record that lists which servers are allowed to send email for your domain. Receiving mail servers check it to help decide whether a message is legitimate. The record ends in an all mechanism whose qualifier sets the default: -all rejects anything not listed, ~all marks it as suspicious, and +all (dangerous) authorises everyone.
SPF limits a record to 10 DNS-lookup mechanisms (include, a, mx, ptr, exists and redirect); exceed it and receivers return a permerror and may ignore your SPF entirely. This tool counts the lookups in the record itself: remember that each include pulls in more, so stay well under 10. The check runs on Uptimeify's EU servers and your input is not stored.
A broken SPF record quietly sends your email to spam. Validate it here, then let Uptimeify keep watch on your domain's DNS and deliverability and alert you the moment a record changes or breaks.
Ready to Keep Your SPF Record Protected?
An SPF record that's right today disappears with the next DNS change. Uptimeify checks the TXT record on an interval against your expected value and reports the change before mail starts bouncing.
