Everything You Need to Know

Cold email run by Astrid Labs has reached more than 46,600 businesses since March 2026, and 411 of them replied asking to hear more. Since March, 126 sales calls have been booked with 87 different businesses, and 69 of those businesses came straight from the cold email. Other builds include an AI system that scores government RFPs and drafts proposals, and a signal engine that finds family businesses near a succession decision.

The first live email goes out in week four at the earliest. Week one builds the buyer list and verifies every address. New sending domains then warm for at least 21 days while the copy is written and approved. After launch, replies and booked calls are reviewed every week and the campaigns are tuned on that data.

No. Astrid Labs does not promise a fixed number of leads before it has seen a market. It reports replies and booked calls every week and tunes the targeting and copy on real data.

B2B service firms with a clear buyer: managed IT and cybersecurity providers, consultants, coaches, accounting advisors and agencies. Builds have also covered a government-contracting consultancy, a family-business advisory firm and a direct-to-consumer supplement brand.

Instantly for sending, Zapmail for mailboxes, Anymailfinder to find and verify addresses, LinkedIn Sales Navigator for buyer lists, GoHighLevel as the CRM, and Claude for research, writing and custom AI systems. Each client's domains, inboxes and data are set up in the client's own name.

Done-for-you cold email means the agency builds and runs the whole system: buyer lists, address verification, sending domains and inboxes, warmup, copy, campaign management and reporting. The client's job is answering the replies and taking the calls.

Astrid Labs builds systems instead of selling hours or impressions. Every campaign is judged by booked calls, every number it reports comes from the system that produced it, and the client keeps the domains, inboxes and data.
