The basics

What is Claude cold email?

Claude cold email means running your outbound through Claude instead of clicking around a dashboard. You add the native HotHawk MCP server as a connector, then tell Claude what you want in plain language.

It drafts the steps, imports and cleans the list, and sends across your warmed mailboxes. HotHawk is the sending layer underneath: inbox rotation, warmup on real Google and Microsoft inboxes, the headroom for 40,000 a day and more, and a Master Inbox where its own AI labels every reply the moment it arrives. Claude is simply how you operate it.

What it does

Everything cold email, in a chat.

Claude handles the writing and the busywork. HotHawk does the sending, the warmup and the rotation, and pulls every reply into the Master Inbox.

Build and send a campaign by asking.

Build and send a campaign by asking.

Tell Claude who you want to reach and what to say. It drafts the steps, imports and cleans the list, then sends it across your warmed mailboxes. No clicking through builders, no copy paste between tabs. You describe the job in a sentence or two and it happens.

Not from one inbox, from all of them.

Not from one inbox, from all of them.

Claude does not send from a single account and hope. HotHawk rotates every send across your mailboxes, keeps warmup running on real Google and Microsoft inboxes, and has the headroom for 40,000 a day and more. The AI runs the campaign. The infrastructure underneath it stays switched on.

Ask for the numbers, get a straight answer.

Ask for the numbers, get a straight answer.

"How is the fintech campaign doing?" pulls the reply and positive counts, per step and per mailbox, in the chat. Every action is a real tool call, so you can see exactly what Claude looked at and what it changed.

Every reply, sorted on arrival.

Every reply, sorted on arrival.

The Master Inbox pulls responses from every mailbox into one view, forwarded and out of office included, and HotHawk's own AI labels each one out of the box: Interested, Not interested, Out of office. Or hand it to Claude to triage, label and draft answers on your own rules for you to approve. Nothing warm gets lost in a thread you forgot about.

Claude cold email FAQs

What is Claude cold email?

It means running your cold outreach through Claude instead of clicking around a dashboard. You connect the native HotHawk MCP server, then tell Claude what you want in plain language. It builds the campaign, imports and cleans the list, sends across your warmed and rotated mailboxes, and helps you work through the replies. HotHawk is the sending layer underneath. Claude is how you operate it.

Is this an AI SDR?

No. An AI SDR is sold as a hands-off agent that runs outbound for you. HotHawk is the execution layer it runs on. You point Claude at it and stay in control, approving what sends, while HotHawk handles the sending, deliverability and reply management. You get the speed of an AI doing the work without handing over the keys.

How is this different from your MCP feature page?

This page is the overview of what you can do with cold email in Claude. The MCP feature page goes deeper on the workflows, and the MCP setup page walks you through connecting the server. Start here, then follow the cross-links.

Does running it from Claude hurt deliverability?

No. Whoever hits send, the same protections stay on. Sending rotates across your mailboxes, warmup runs on real Google and Microsoft inboxes, and open and link tracking stay off for everyone. Claude runs the campaign, but it cannot switch off the practices that keep your sending healthy.

Do I need to write code?

No. Add the MCP connector and everything runs in plain language from the chat. If you would rather build your own thing, every action is also a REST endpoint, so your own code can call the exact same tools.
