Reply to Intercom & HubSpot conversations from Slack threads

BackReply turns each conversation notification into a Slack thread you can safely respond in—then syncs replies back to Intercom or HubSpot.

A real reply flow (not just notifications)

  • Reply in-thread (keeps context)
  • See delivery status (sent/synced)
  • Jump to the source conversation when needed
