Labels apply the moment a reply arrives. Change any of them by hand.

Intent labels

Hot leads surface first

The AI reads every reply and labels it, so the interested ones rise to the top and out-of-office noise stays out of the way.

Pipeline

Move the deal without leaving the thread

Each reply can become a deal. Drag it through stages, add a value and watch pipeline build, right next to the conversation.

  • Stages from Interested to Won
  • Deal values roll up into pipeline totals
  • Syncs with the full CRM
“Yes, let’s find time this week.”

Team assignment

The right rep, and never two at once

Route conversations to the right person, leave internal notes and see who is already replying. Collision detection warns before anyone double-replies a prospect.
