We'll fetch the live SPF record and let you view, understand, and edit each mechanism — then generate your final record.
What this tool does
1
Look up your existing SPF record
Enter a domain and we'll fetch the live TXT record from DNS and parse every mechanism.
2
Understand each part in plain English
Every include:, ip4:, mx, and ~all is explained so you know exactly what your record authorizes.
3
Add, edit, or remove mechanisms
Build your record step by step. The DNS lookup counter updates in real time so you stay under the 10-lookup limit.
4
Copy your finished record
Get a validated, publish-ready SPF record to drop into your DNS provider.
