Know instantly when your email authentication breaks
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.
DeliveryRadar is a SaaS tool that monitors email authentication protocols (SPF, DKIM, DMARC, TLS-RPT) daily and alerts users to any issues. It offers a free instant scanner and a subscription service for continuous monitoring at $19 per month.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
