The Verdict

Postmark is the gold standard for transactional email deliverability. Built by developers who understand that emails failing to arrive is a critical business problem, Postmark prioritizes inbox placement (98%+ consistently) and transparent pricing. The free Developer tier is unlimited and never expires—great for testing. Paid plans start at $15/month for 10,000 emails.\n\nIndie hackers choose Postmark when deliverability is mission-critical: SaaS companies sending password resets, ecommerce platforms sending order confirmations, or financial services sending account alerts. The pricing is higher than budget alternatives, but the premium is justified by industry-leading uptime, detailed bounce tracking, and human support that actually helps. Postmark includes inbound email processing on Pro+ tiers, making it versatile. Perfect when you can't afford to lose emails in spam folders.
