Tell Claude instead of clicking it
Frostbreaker plugs into Claude as a connector. Your own workflows and skills reach it from there.

create_campaignPublishes it to Instantly, minus opt-outs and the suppression list
publish_campaign
That is how 1,227 leads ran through here on 27 August: 883 website findings, six campaigns, in one day.
The connector does not start a search and it does not send. The campaign sits ready in Instantly and waits for you to press start.
Who it's for

We set the price together
It depends on your client count, not on your leads and not on your workspaces. Named on the first call, cancel monthly, no setup fee.
Lookups run through your own accounts, at cost price. We add not a cent.
Frequently asked questions
Why not go straight to Apollo or Hunter myself?
Because the address is the start, not the result. Apollo delivers decision makers with a verified address. The work begins after that: an opener per contact, a check on the copy, a match against your suppression list and existing customers, the sending, the LinkedIn message and the call when the lead doesn't reply, and finally the question of which copy version booked meetings. All of that sits between Apollo and Instantly, and that is what Frostbreaker does.
What do I need to get started?
Your own accounts with the services running in the background: Google for the map search, OpenAI for the research, Hunter and Apollo for addresses and decision-makers, Prospeo as a further source, NeverBounce for verification and Instantly for sending. You enter the keys once in settings, stored encrypted. After that every lookup runs on your own accounts, at cost, and we add not a cent. After every search the dashboard shows to the cent what it cost. What the monthly amount itself costs sits further up this page.
Can I cancel anytime?
Yes, monthly, no minimum term, no notice period beyond the current month.
Won't every email sound the same then?
The frame is the same, the line that matters is not. The opener is written per recipient out of what was researched about that particular company, not dropped in from a placeholder. On top of that, every step comes in two versions, and they have to differ in approach: different angle, different question, different opening sentence. Two versions that differ by two words get flagged as one and the same. And anything lifted word for word out of your offer is caught when the copy is measured, because at that point the recipient is reading a stranger's bullet points.
Can I still change the copy?
Yes. Nothing goes out before you have seen it: the eight pieces of copy sit in the campaign form and wait there. You can overwrite any step or refine it with a plain instruction, so shorter, more direct, or turn this into a break-up email, one step at a time rather than the whole sequence at once. Whatever you leave alone stays exactly as it is. Before any copy goes to a thousand addresses, a person has read it.
How fast can I get started?
The first search runs the same day. Two to four weeks pass before the first campaign goes out. That is how long fresh mailboxes need to warm up, and no tool gets around it. That is exactly why there is no 14-day trial: it would be shorter than the setup. We set things up together on the call and stay with you through the first campaign.
What happens to my data if I cancel?
Your data is deleted after the contract ends, or returned on request, as governed by the DPA. There's no automatic continued use after cancellation.
