Postmark vs Suped

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.

Suped is a web platform for monitoring email authentication and deliverability across DMARC, SPF and DKIM. It aggregates DMARC reports into visual summaries of sending sources and authentication results, and detects configuration problems with steps for addressing them. Hosted options include DMARC, SPF, DKIM and MTA-STS, as well as SPF flattening and BIMI setup and hosting. The service checks sending IPs against major blocklists and can alert customers when an IP is listed. Email and webhook alerts cover new senders, declining authentication rates and domains falling out of policy. MSP features include separate client workspaces, bulk migration support, API access and white-label reports. A HaloPSA integration can import MSP clients and create tickets for open issues; PSA integrations are in beta. Free covers one domain, up to 1,000 emails per month and 14 days of report retention, with unlimited users and no credit card required. Business costs $19 a month with an annual discount; the page also shows $24. Suped was founded in 2025 and is headquartered in Sydney, Australia.
