Email Deliverability Monitor

Replaces a $65k SDR's wasted hours. Watches SPF/DKIM/DMARC daily, alerts before bounces.

The Problem

An SMB owner spends $65k/yr on an SDR running outbound — but the moment their sending domain's SPF/DKIM/DMARC drifts (DNS edit, new ESP, expired DKIM key), inbox placement collapses and sequences silently fail. By the time the SDR notices the reply rate dropped to 0%, two weeks of pipeline are gone.

The Outcome

Daily cron fires → agent scans every operator-owned sending domain (primary + lookalikes) for SPF/DKIM/DMARC/BIMI alignment → diffs against last week → flags broken records, expired keys, missing DMARC, or DNS drift to Slack with the exact zone-file fix. Catches deliverability collapse the same day, not the same fortnight.

Day in the Life
1.
Mon 6am: scans 8 sending domains → finds DKIM selector google._domainkey on bestrevops.co returns NXDOMAIN → posts Slack #deliverability with copy-paste TXT record
2.
Wed 6am: detects DMARC policy on signalaeo.com flipped from p=none to p=quarantine → flags p=reject upgrade path
3.
Fri 5pm: weekly digest — SPF includes count, DMARC alignment %, DKIM key age, BIMI eligibility, predicted inbox placement trend
