DeliveryRadar
Know instantly when your email authentication breaks
Get picks like this daily. Today's launch numbers, the top launches, AI and tech news, and a daily opportunity pick, straight to your inbox.
DeliveryRadar watches your domain’s SPF, DKIM, DMARC, and TLS-RPT setup every day and emails you the moment something breaks: a new source failing, a record someone quietly changed, weak enforcement nobody caught. Built by a 2-person IT shop that found its own email authentication silently broken for months — these are the same checks we built to protect ourselves. Free instant scanner (no signup), or continuous monitoring with trend tracking and sender lookup for $19/mo.

Could you build this?
Yes Daily DNS lookups of SPF, DKIM, DMARC, and TLS-RPT records with change detection and email alerts are well-defined and buildable with standard tools. Parsing DMARC aggregate reports is more work but still standard.
