The differences that matter.
Full marketing stack
Resend stopped at transactional email. nitrosend gives you campaigns, automations, flows, segmentation, and analytics -- everything you need for email marketing, plus transactional sending.
AI does the work
Resend has no 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
Resend has a great API but no MCP support. nitrosend works from Claude, ChatGPT, Cursor, Codex, or Gemini. Your AI agent talks directly to nitrosend via MCP. No code needed for marketing tasks.
Contact management built in
Resend has no contact management, no lists, no segments. With nitrosend you get unlimited contacts, audience segmentation, and behavioral targeting out of the box.
