Fraudmarc vs Postmark

Fraudmarc provides brand and customer protection services centered on SPF, DKIM, and DMARC email authentication. It manages and monitors authentication policies and provides free DMARC reports. Its SPF Compression service imports and compresses existing policies, gives users a panel for adding email vendors, and dynamically updates flattened policies when customers or vendors make changes. The service is designed to help address SPF's 10 DNS lookup limit while keeping policies within specification limits. DMARC tools include hosted report analysis, automated analysis, and SenderTrace Intelligence, which identifies people and departments behind email sources. Fraudmarc also lists free SPF record and DMARC policy checkers, and makes its Community Edition DMARC Analyzer available on GitHub. It offers web and self-hosted access. DMARC Standard includes 30-day history for $21 per month when billed annually; Advanced is $4 per user per month billed annually and includes 90-day history. SenderTrace Intelligence is $12 per user per month billed annually and includes one-year history. SPF options start at $2 per month.

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.
