Email built for your AI agent.

nitrosend was MCP-first from day one. 21 tools, one install, every AI agent. Claude, ChatGPT, Codex, Cursor, Gemini, all of them.

$ claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp

Every agent. One install.

nitrosend is MCP-native. That means any agent that speaks the Model Context Protocol can do your email marketing for you. Set up a sender, write a campaign, segment your list, send a flow, all in conversation.


It's not a plugin. It's the primary interface.

nitrosend is the fastest email platform that works where you work. Prompt it from Claude. Trigger it from your code. Let it run your email marketing while you build your product.

It's not an email tool with AI features. It's an AI that does your email marketing.

We're obsessed with speed. Not because speed is trendy, but because speed is the thing that separates the people who ship things that change lives from the people who plan to ship. Every minute you spend configuring email automations is a minute you're not talking to customers, writing code, or selling.

We believe the best tools disappear into your workflow. You shouldn't have to learn our interface.

We're George, Ed and Kam, and we're building nitrosend because the world has shifted and email hasn't caught up. Until now - welcome to faster email.
