DMARCLY vs Mail-Tester

DMARCLY is an SPF, DKIM and DMARC monitoring service for tracking email authentication and helping block spoofing and phishing. It parses incoming DMARC XML reports and presents charts in a dashboard, with aggregate views by domain, source, organization, result and country. Safe SPF addresses validation failures caused by SPF’s 10-DNS-query limit and is described as requiring no manual maintenance. Security features include two-factor authentication, PGP encryption for forensic reports, and MTA-STS/TLS reporting for issues involving unencrypted connections. Adaptive blacklist monitoring checks outbound IP addresses against Spamhaus ZEN, SpamCop Blocking List, Barracuda Reputation Block List and Passive Spam Block List. An MSP dashboard supports multiple clients. A REST API covers aggregate and forensic reports, Safe SPF and domain creation. DMARCLY runs on web and API platforms. Pricing starts at $17.99/mo with a 14-day trial; there is no free plan.

Mail-Tester checks an email, its mail server, and sending IP, then gives a spam score and reports configuration findings. To run a test, send a message to an address generated by the service and open the result page. Checks include blocklists, SpamAssassin, SPF, DKIM, Sender-ID, DMARC, links, and pictures. The free plan allows three tests within a rolling 24-hour period. A test counts after a new message is sent, the result page is requested, and the result is returned successfully; reopening that result does not use another test. Free results remain available for 7 days. With an account using its own prefix, results remain available for 30 days. Accounts also provide white-labeling, result-page CSS customization, statistics, a 30-day test listing, and pages without ads. Paid plans include an iframe and JSON API for integration; API output can include message details, authentication checks, body analysis, blacklist results, and broken links. One-time test bundles cost $5 as a one-time purchase to $250, paid once; monthly plans cost $10 a month to $250 a month. Passing does not guarantee inbox placement.
