  • SPF record built from your senders
  • DMARC record with policy and report address
  • Live SPF lookup counting per RFC 7208
  • Include tree for troubleshooting

How to read the result

Generated records run in your browser; nothing is sent to us. The validator reads your live SPF and counts DNS lookups so you can fix "too many lookups" errors.

Frequently asked questions

What is the 10 lookup limit?

SPF evaluation may trigger at most ten DNS-querying terms. Beyond that receivers return a permanent error. See how to fix it.

Which DMARC policy should I use first?

p=none with a report address, then tighten as your reports show every legitimate sender passes.

Can I have two SPF records?

No. A domain must publish exactly one SPF record; merge them into one.
