SPF Generator
Add your senders and get an SPF record that stays within the limit of 10 lookups.
Analysis messages from the checker are currently in Dutch.
How does it work?
Enter your domain, add the services that send on your behalf (for example spf.protection.outlook.com) and choose the end of the record. We build the TXT record.
Frequently asked questions
What do I enter under includes?
The SPF name of your mail provider, for example spf.protection.outlook.com for Microsoft 365 or _spf.google.com for Google.
What do I choose for the end?
~all if you are not yet sure of all senders, -all to reject everything else.
Why a maximum of 10 lookups?
That is the limit in the SPF standard. Above it the record stops working.
