Frequently asked questions
Where do I publish the SPF record?
As a TXT record on the domain itself (host "@" or the bare domain) at your DNS provider. Replace any existing v=spf1 record instead of adding a second one.
Is this generator free?
Yes, always — it runs entirely in your browser and does not count toward your daily checks.
