Domain & DNS monitoring for MSPs and agencies: a daily expiry guardian plus 14 automated health checks — TLS, email auth (SPF/DKIM/DMARC/MX), DNS, DNSSEC, web security and blacklist reputation — graded A–F, re-checked daily, with email alerts the moment anything slips. From $99/mo, 14-day free trial.

Hey PH 👋 I built Domain Watchdog after watching an agency lose a client's site to a domain that silently expired — the registrar's renewal notice went to the client (whose card had changed), and nobody told the agency until the site went dark. Registrars remind the owner. Nobody reminds the person actually responsible. So Domain Watchdog does: it watches every client domain across every registrar and warns you at 60/30/14/7/1 days before expiry. It grew from there into a full daily health check — TLS, DNS, email auth (SPF/DKIM/DMARC), web security, blacklists — each domain graded A–F, white-labeled per client, with alerts into email/Slack/Teams or your PSA. Would love your feedback, especially from other MSPs and agencies.

How does the alerting work if you're monitoring a few hundred domains across multiple clients — does it bucket by client or just blast everything to one inbox?

Daily expiry alerts have saved me from at least two client renewals slipping through the cracks, and the A-F grading makes it easy to explain issues to non-technical folks.
