From Zero to 200 Personalized Emails: Autonomous Sales Prospecting

David Park|February 28, 2026|7 min

Sales prospecting is one of the most time-consuming tasks in any go-to-market motion. Finding leads, researching companies, crafting personalized messages, and sending them takes hours per batch. We gave Coasty the entire pipeline.

The Workflow

  • Searched LinkedIn and company directories for matching prospects
  • Researched each company's product, recent news, and tech stack
  • Identified the right contact person at each company
  • Wrote a personalized email referencing specific company details
  • Sent emails through the user's email client
  • Logged each outreach in a tracking spreadsheet

Every email was different. Coasty referenced specific products, recent blog posts, and company milestones. No templates, no mail merge.

Quality Over Quantity

The goal was not to blast generic emails. Each message demonstrated genuine understanding of the prospect's business and a clear reason for reaching out. Coasty spent 2-3 minutes per prospect on research before writing anything.

Autonomous prospecting is not about replacing the human touch. It is about giving every prospect the personalized attention they deserve, at a scale that no human team can match.
