SPF
Name: example.com
Type: TXT
Value: v=spf1 a mx include:_spf.example.net ~all

DMARC
Name: _dmarc.example.com
Type: TXT
Value: v=DMARC1; p=none; adkim=r; aspf=r; pct=100; rua=mailto:[email protected]

Start DMARC enforcement carefully and verify every legitimate sender. DKIM keys must be generated by your mail provider, so this tool does not invent them.

How it works

SPF / DMARC Generator is designed to give you the result immediately. The calculation or processing happens on your device for this tool, so normal use does not require an account or a file upload.
