Audit hundreds or thousands of domains for email-spoofing risk in one run. For each domain you get the SPF record and its all policy, the DMARC policy (p=), MX hosts, a list of flagged issues, and a 0-100 score.
Who it's for
- MSPs and IT consultants checking client domains or prospecting new clients
- Sales and lead-gen teams qualifying prospects with weak email security
- Security teams monitoring a domain portfolio
Input
domains: a list of domains. URLs and email addresses are cleaned to the bare domain, and duplicates are removed (up to 10,000).concurrency(optional): parallel lookups, default 10, max 50.
{ "domains": ["google.com", "example.com"] }
Output
One dataset row per domain:
{"domain": "example.com","spf": "v=spf1 -all","spfAll": "-all","dmarcPolicy": "reject","mx": [],"nullMx": true,"issues": [],"score": 100,"checkedAt": "2026-10-15T01:00:00.000Z"}
Flagged issues include missing SPF, +all or no all, multiple SPF records, missing DMARC or a missing p=, p=none, and no MX. Domains that fail DNS lookup land under errors with score: null, so you never get a false "missing record" result.
Pricing
Pay per event: $2 per 1,000 domains audited ($0.002 each). Lookups that error out aren't charged.
Notes
Lookups use system DNS with a DNS-over-HTTPS fallback. Results show public DNS at run time.
