Writes cold emails that get replies

Each message references something real about the prospect. Their recent hire, a funding round, a pain point from their job posting. Response rates 3-5x above industry average.

Follows up and books meetings

Coldline handles the back-and-forth. It responds to replies, answers objections, and schedules directly to your calendar. You just show up.

  • 40-50 emails per day maximum
  • 3 months to ramp up

Coldline

  • $49/mo. Cancel anytime.
  • Hundreds of personalized emails daily
  • Live in minutes
  • Every message built from real research
  • Runs 24/7. Zero overhead.

Your first sales hire
should be artificial
