Nitrosend

Nitrosend is an AI-native email platform designed so marketers, developers and AI agents can create and operate email campaigns through natural-language instructions rather than relying primarily on traditional drag-and-drop email builders. It supports transactional email, newsletters, automated flows, contact management, segmentation, analytics and brand-matched email design. Its MCP integration allows AI tools such as Claude, ChatGPT, Codex, Gemini and Cursor to create campaigns, build flows, manage contacts and inspect analytics. Nitrosend also provides a REST API and CLI for custom applications. Its NitroWheel LLM analyzes email performance and continuously optimizes elements such as subject lines, content and send times. Users can bring their own sending infrastructure, including SendGrid, Postmark, Resend, Mailgun or Amazon SES, as well as their own OpenAI or Anthropic keys. Nitrosend is currently active. No general country-specific restriction was identified; availability can depend on the user's email provider, domain and local regulations.
