The basics
What is an AI cold email workflow?
An AI cold email workflow is letting a model like Claude do the hands-on work in your cold email tool: spinning up campaigns, working through replies and pulling reporting, all from plain-language instructions instead of clicking through screens.
HotHawk makes this real with a native MCP server, built on the open Model Context Protocol. You connect it to Claude once, then drive your whole cold email operation by asking. To set it up, head to the MCP server page, and if you would rather build directly, it is all in the API too.
How it works
Run cold email from a simple conversation.

What is an AI cold email workflow?
It is letting an AI model like Claude do the hands-on work in your cold email tool: spinning up campaigns, working through replies and pulling reporting, all from plain-language instructions. HotHawk makes this possible through a native MCP server.
What can Claude actually do with HotHawk?
Launch campaigns and add leads, find and reply to positive responses in your master inbox, check mailboxes and warmup, and pull analytics, all by asking. Access is granted at the account level, so you tell it which workspace to work in.
Is this an AI SDR?
It gives you a lot of what people want from an AI SDR, without handing over the keys. You stay in control and direct the work, while Claude handles the repetitive parts of running cold email through HotHawk.
Do I need to write any code?
Not at all. The MCP server is added as a connector in Claude in a couple of minutes. If you would rather build directly, the HotHawk REST API is there instead.
How do I connect it?
You add HotHawk as a custom connector in Claude Desktop or the Claude web app. The full step-by-step is on the MCP server page.
