Continuous monitoring & drift alerts

Your domain's email security posture changes silently — a record gets edited, a sender is added, SPF blows the 10-lookup limit. We watch every day and tell you the moment something drifts.

Plan-tiered cadence

Starter rescans daily; Pro every 6 hours. Manual “Rescan now” whenever you want a fresh read.

Field-level drift

We don't just compare scores — we diff the SPF record, the DMARC p=, the MX host list, the DKIM selector set. Status flips and policy weakenings surface with full context.

Three alert channels

Email (every member), Slack (Pro), and a generic outbound webhook (Pro). Toggle each channel from settings.

Weekly digest

Monday morning summary email — total scans, drift events, regressions per domain. Suppressed if nothing happened.
