One MCP. Every agent.

nitrosend speaks the Model Context Protocol natively. Any MCP-compatible agent can run your campaign and lifecycle stack. We don't have a "Claude integration" and a "ChatGPT integration". We have one MCP server that works everywhere.


If your agent speaks MCP, it speaks nitrosend.

nitrosend is the fastest email platform that works where you work. Prompt it from Claude. Trigger it from your code. Let it automate email marketing across the brands, products, and clients you manage in Codex.

It's full stack email automation inside your AI agent, not an email marketing tool with AI added.

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.
