SPF record generator: frequently asked questions
What is SPF?
Sender Policy Framework: a DNS record listing the servers allowed to send email for your domain, which helps stop spoofing and spam-folder delivery.
Can I have two SPF records?
No. Multiple SPF records make SPF fail. Merge everything into one.
~all or -all?
Start with ~all (soft fail). Move to -all once you are sure every legitimate sender is listed.
What is the 10-lookup limit?
SPF allows at most 10 DNS lookups. Each include can trigger several, so remove services you no longer use.
Is SPF enough?
No. Add DKIM signing and a DMARC policy too — Gmail and Yahoo require them for bulk senders.
Where do I add the record?
In your DNS provider (Cloudflare, your registrar or host) as a TXT record on @.
Why do results differ from another checker?
DNS and web responses are cached for their TTL and may differ by location. Our checks use Cloudflare’s 1.1.1.1 resolver.
Is the spf record generator free?
Yes. It is free with no sign-up and no usage limits for normal use.
Is my data sent to your servers?
No. This tool runs entirely in your browser, so what you type never leaves your device.
Does it work on my phone?
Yes. The tool works in any modern browser on iPhone, Android, tablet or computer.
