Coldr is an AI agent that runs your entire cold email outbound campaign — finds your best prospects, researches them deeply, personalizes every message, and follows up until they reply.
Describe your ideal customer in plain English. Role, company size, industry, tech stack — whatever matters to your sale. Coldr learns your ICP instantly.
Coldr scours LinkedIn, company databases, and public signals to find every prospect matching your ICP. Then it reads their recent posts, company news, and bios — to write every email like it personally researched them.
Coldr sends your personalized emails through a pool of warmed inboxes, follows up on your schedule, and stops when prospects reply. You only jump in when someone answers.
Volume-focused tools killed cold email's reputation. When you personalize at scale and target the right people, open rates double. The channel isn't dead — the approach was.
Basic AI tools scrape LinkedIn bios and call it research. Coldr reads actual company news, recent posts, and product context — then writes an email that sounds like you spent 20 minutes on it. Because it did.
Coldr manages your warmup rotation, inbox rotation, and sending volume automatically. It learns which settings get you past spam filters and adjusts daily. You stop worrying about your domain reputation.
Cold email tools had five years to add AI.
They added a button that generates your prompt.
That's not AI-native — that's a feature, not a rebuild.
The best SDR on your team isn't the one who sends the most emails. It's the one who researches every prospect, writes like they actually care, and follows up at exactly the right moment. Coldr is that SDR — multiplied. It never sleeps, never rushes, and never sends the same email twice.
We built Coldr because we were tired of tools that automate sending without automating thinking. The world doesn't need another email scheduler. It needs an outbound agent that actually works.
Coldr runs while you sleep. Your first campaign can be live in under an hour.
