DMARCLY vs Postmark

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.

Postmark delivers and tracks application email as an alternative to SMTP or Sendmail. It separates transactional and broadcast messages into different Message Streams and IP infrastructure. Developers can send through REST API, SMTP, or multi-region SMTP routing, with official libraries for Node.js, Python, Rails, Ruby, PHP, and.NET. Inbound messages can be converted to JSON and sent to a webhook URL. Tracking includes delivery, bounces, spam, opens, and links, with event webhooks. Editable responsive templates cover transactional messages such as password resets, receipts, and invitations. The free Developer plan costs nothing, provides 100 emails per month, permits no overages, and does not expire. Basic starts at $15 a month for 10,000 emails per month; extra emails cost $1.80 per 1,000 and are calculated at the end of the billing cycle. Unused emails do not roll over. Postmark lists API and web access. Its iOS app was sunset in June 2025 and is no longer supported.
