# What happens if I receive a reply in a campaign?

When a lead replies to a campaign, ReachBoost automatically adds the reply to your Unified Inbox. AI also assigns a lead stage based on the reply.

### Automatic lead stages

ReachBoost analyzes the reply and assigns one of the following lead stages:
* Not Interested
* Engaged
* Interested
* Hot Lead

This helps you quickly understand how interested the lead is. More information about lead stages [here](https://help.reachboost.io/en/article/how-to-categorize-leads-using-lead-stage-tags-q3drdh/).

**Note:** Always check that you are in the correct client workspace before reviewing campaign replies.
