The differences that matter.
Full marketing stack
Postmark is excellent at transactional delivery but has no marketing campaigns, no automations, no flows. nitrosend gives you the complete email marketing stack plus transactional sending in one platform.
AI does the work
Postmark has zero AI capabilities. nitrosend's AI agent writes your campaigns, designs your emails, builds your segments, and optimizes your sends. You review. It executes.
MCP-native
Work from Claude, ChatGPT, Cursor, Codex, or Gemini. Your AI agent talks directly to nitrosend via MCP. No browser needed. Postmark has no MCP support and no plans to add it.
One platform, not two
With Postmark you still need a separate ESP for marketing. nitrosend handles transactional and marketing email in one platform with one API, one dashboard, and one bill.
