Why Use This Tool

Frequently Asked Questions

Can I generate multiple record types at once?
No — one type per request. Make separate calls for SPF, DMARC, etc.
What SPF policy should I use?
Start with `~all` (softfail) during testing, then switch to `-all` (hard fail) once you've verified all legitimate senders are included.
What's a good DMARC starting point?
Start with `p=none` and `rua` set to receive aggregate reports. Once you see all legitimate email passing, move to `quarantine` then `reject`.
