AI cold email
AI cold email, done properly.
Your model can write the emails and pick the leads. It still needs something to send them: the inbox rotation, the warmup, the infrastructure to do 40,000 a day and more. That is HotHawk. Run it from Claude over MCP, or build it into your own agent with the API.

What is AI cold email?
AI cold email is using AI models to run the manual work of cold outreach: writing and personalising the emails, choosing who to contact, and handling the replies. The AI does the thinking and drafting. A sending platform does the actual sending, warmup and deliverability underneath. HotHawk is that platform, built to be run by AI.

Most AI cold email tools are wrappers that draft copy and hand you a file. The sending, the warmup, the mailbox rotation and the replies are still your problem. HotHawk is the other half: the infrastructure that turns what the AI wrote into 40,000 emails a day and more, going out across rotated mailboxes and coming back to a Master Inbox where its own AI labels every reply.
We are not an AI SDR that decides for you. We are the cold email software an AI SDR runs on, with you holding the launch button.
AI cold email FAQs
What is AI cold email?
AI cold email is using AI models to run the manual work of cold outreach: writing and personalising the emails, deciding who to contact, and handling replies. The AI does the thinking and drafting; a sending platform like HotHawk does the actual sending and deliverability underneath it.
Is HotHawk an AI SDR?
No, and that is deliberate. HotHawk is the cold email software an AI SDR or AI assistant runs on. You point Claude or your own agent at it and direct the work, while HotHawk handles the sending, warmup, rotation and reply management. You keep control of what goes out.
How does AI connect to HotHawk?
Two ways. Claude connects through the native MCP server, added as a connector in a couple of minutes with no code. Any other model or custom agent connects through the REST API, which exposes the same actions as the app.
Where should I start?
If you want the overview, read the AI cold email software page. If you want to try it hands on, connect the MCP server and follow one of the how-to guides, like launching a campaign from Claude.
