The Uptime Monitor allows to set up real-time monitors for testing DMARC, SPF, and DKIM records, IP addresses, TLS, HTTP, and TCP availability.
DMARC Analytics automatically activates the Uptime Monitor and creates system monitors for testing your domain’s SPF, DKIM, and DMARC records every 2 hours. System monitors are free as long as they work at the interval of 2+ hours.
