In their own words
DMARC Report
DMARC Report processes aggregate and forensic DMARC reports, showing authentication results and sending sources in dashboards. It monitors SPF, DKIM, and DMARC records for changes, failures, and other issues, with alerts by email, webhook, or Slack. Forensic analysis adds per-message details such as sender IP, header information, authentication failures, and receiver disposition. Teams can use it while moving domain policies toward quarantine or reject. The service includes AI analysis, a REST API, and MCP integration for compatible tools including Claude and ChatGPT. MSPs can manage client domains through a multi-tenant portal with white-label reports, role-based access, and bulk onboarding. The free Core plan covers one domain and 10,000 messages per month, with 30 days of history and aggregate reports. Paid plans start at $25/mo; listed plans add message capacity, domains, history, and reporting or access features. The website also offers free checks for DMARC, SPF, DKIM, BIMI, and MTA-STS without signup. Founded in 2014, DMARC Report is headquartered in California.
Postmark
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.
