What it can do
| Tool | What it says it does |
|---|---|
check_dmarc | Check a domain's DMARC, SPF, and MX records. Use this to diagnose email authentication issues. |
check_email_health | Get a 0-100 email health score for any domain. Checks DMARC, SPF, MX, and DKIM records and returns a letter grade (A+ to F) with actionable recommendations. Use this to audit any domain's email security posture. |
check_health | Check ARC-Relay service health and uptime. |
check_spf | Validate a domain's SPF record. Shows mechanisms, DNS lookup count, and warns if over the 10-lookup limit. |
network_leaderboard | View top relay nodes ranked by reputation score. Filter by region. |
network_stats | Get public relay network statistics — total nodes, active nodes, messages routed, delivery rate, and the average DMARC rate nodes report about themselves (rates are null until there is traffic). |
In its maker's words
Checks any domain's DMARC, SPF, MX and DKIM setup, scores it 0-100, and ranks the fixes.
