How this works

01

Paste or upload

Drop up to 100 domains. One per line, or upload a CSV / XLSX / TXT file. We'll figure it out.

02

We check the records

Server-side parallel DNS queries against DMARC and SPF records. No browser-side limits, no rate limiting on you.

03

You get answers

Status, policy, raw records. Export to CSV. Done in under a second for most batches.
