Reply.io lets sales teams build multichannel outbound from one workspace: prospect from a B2B database of 1+ billion contacts, run conditional email and LinkedIn steps, and manage replies from a unified inbox. The product also sells mailboxes with built-in warmup so you can buy domains, connect inboxes, and start sending without juggling separate deliverability tools.

Where many sequencers stop at email templates, Reply.io layers an optional Jason AI SDR agent that researches prospects, writes personalized copy, handles replies, and books meetings on autopilot or in approval mode. Reply.io also exposes an API and MCP integration so you can launch outbound from Claude, Cursor, or Codex without opening the dashboard. That terminal-first angle is unusual for a category dominated by browser-only campaign builders.

Reply.io fits outbound sales reps, SDR teams, and agencies running cold email at volume. Common workflows include list building from intent signals, multichannel nurture sequences, and agency client workspaces with role-based access. The Agency Core plan at $210 per month supports multiple client workspaces under one agency account.
