How It Works

  1. Connect your outreach - Link your cold-email platform via webhook. Every send, reply, and bounce from EmailBison (and more soon) syncs automatically.
  2. Train your agent - Add knowledge base articles, golden replies, and tone settings. Test in the Playground until the AI sounds like you.
  3. Set your threshold - Choose your intent threshold (1-10) in Skills. Toggle Full Auto or Review Mode. Enable follow-up sequences.
  4. Close more deals - InboxSDR scores every reply, auto-responds to qualified leads, follows up with silent ones, and surfaces hot leads for you to close.
