AI cold email software that actually sends.
Loads of tools help AI write a cold email. Hardly any handle the hard part, which is actually sending it. That is HotHawk. Inbox rotation, warmup, and the infrastructure to push 40,000 a day and more, all run from Claude or your own agent.

The basics
What is AI cold email software?
AI cold email software uses AI for the manual parts of cold outreach: writing the emails, researching and personalising per lead, and working through the replies.
Most tools stop at the writing. HotHawk is the part that sends it, which is the bit most people underestimate. Inbox rotation across every mailbox, warmup on real Google and Microsoft inboxes, 40,000 a day and more, and a Master Inbox that puts every reply in front of a person. You bring the AI, we run the sending underneath it.
What it does
Where the AI stops, HotHawk starts.
Your model writes the emails and decides who gets them. HotHawk is what actually sends them, keeps your deliverability healthy, and catches the replies.
AI writes. HotHawk sends.
Let your model draft the copy and research the leads. HotHawk is the infrastructure that sends it: inbox rotation across every mailbox, warmup on real inboxes, and the headroom to push 40,000 a day and more. The writing is the easy half. This is the hard half, done for you.
A different email for every lead.
Custom variables let AI research a real detail per lead and merge it into the copy, so ten thousand emails read like ten thousand emails, not one template with a name swapped in. Personalisation and volume stop fighting each other.
Run the whole thing from a chat.
Connect the native MCP server and run HotHawk from Claude: launch campaigns, work through replies, pull the numbers, all in plain language. Every action is a real tool call, so you can see exactly what it did.
Every reply, labelled on arrival.
HotHawk's own AI reads each response the moment it arrives and labels it: Interested, Not interested, Out of office, or a label you add yourself. The warm ones sit at the top instead of buried under auto-replies. Switch on round-robin and each one goes to a rep. Your AI never quietly loses a lead in a thread it forgot about.

Real jobs, real prompts, and the exact HotHawk tools behind each one.
What you get
AI on top, real infrastructure underneath.
Real send volume.
Send 40,000 a day and more across warmed, rotated mailboxes, not a trickle from the one account an AI SDR bolts on.
Two ways in.
MCP for a setup you run from a chat in minutes, or the REST API to build HotHawk straight into your own agent.
You keep the keys.
The model does the work, you approve the send. All the upside of an AI SDR, none of the black box.
AI cold email software FAQs
What is AI cold email software?
AI cold email software uses AI to do the manual parts of cold outreach: writing the emails, researching and personalising per lead, and working through replies. HotHawk is the piece that then sends it, at volume, across warmed and rotated mailboxes, with every reply auto-labelled and put in front of a person.
How is HotHawk different from an AI SDR?
An AI SDR is sold as a hands-off agent that runs outbound for you. HotHawk is the infrastructure that agent needs to actually send. You point Claude or your own AI at it and stay in control, while HotHawk handles the sending, deliverability and reply management underneath.
Which AI models does it work with?
HotHawk has a native MCP server for Claude, added as a connector in a couple of minutes. Every feature is also a REST endpoint, so ChatGPT, a custom agent or your own code can call the exact same actions.
Does letting AI send cold email hurt deliverability?
Not on HotHawk. Whoever hits launch, sending rotates across your mailboxes, warmup runs on real Google and Microsoft inboxes, and open and link tracking stay off for everyone. The AI runs the campaign, but it cannot switch off the protections underneath it.
Do I need to write code to use it?
No. Connect the MCP server and everything runs in plain language from a chat. The REST API is there for teams who want to wire HotHawk into their own stack.
