Every agent. Every provider.

Nitrosend is MCP-first and provider-agnostic. Pick your AI stack, bring your own sending and AI keys, sync your CRM. One install, every integration.

The honest reason this list exists: email marketing is moving from a person operating a dashboard to an agent that drafts, brands and sends it end to end. Whichever agent below you already use, Nitrosend is what it should be running on, not a template editor bolted onto the side.

AI agents

Run email from anywhere you prompt.

One MCP server. Every MCP-compatible client. OAuth auth, no API keys in shell history.

Email & CRM providers

Bring your own stack.

On Pro, Ultra and Enterprise, plug in your sending keys, AI keys and CRM. Same Nitrosend platform, your infrastructure, zero double-pay.

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.
