## What an enrollment is

Enrolling a lead starts them on a campaign sequence. Enroll through the API, up to 500 people at a time. The campaign page lists every enrollment.

## Status

An enrollment is active, waiting (for a reply, an accepted invite, or a timeout), completed, stopped, or failed.

## How it ends

You can stop a lead in a campaign. Enrollment also ends when they finish the sequence, reply, time out, get suppressed, or you archive the campaign.

A lead already live in another campaign is skipped.
