What is SPF?
Sender Policy Framework (SPF) is an email authentication protocol that allows domain owners
to specify which mail servers are authorized to send email on behalf of their domain.
Why do I need it?
Without SPF, spammers can easily spoof your domain and send fraudulent emails that appear to
come from you. This damages your reputation and causes legitimate emails to be marked as
spam.
How does it work?
Receiving mail servers check the SPF record in your DNS. If the sending IP address isn't
listed in your SPF record, the email may be rejected or flagged as spam.
What does an SPF record checker test? +
It looks up the SPF TXT record published for a domain and shows which mail servers are authorized to send email for that domain.
Can SPF alone stop spoofing? +
No. SPF helps identify authorized sending servers, but it should be paired with DKIM and DMARC for stronger protection against spoofing and phishing.
How often should I check SPF records? +
Check SPF whenever you add or remove an email provider, change DNS, or investigate deliverability problems. Continuous monitoring helps catch accidental changes sooner.
