Once a cadence is in progress, you will be able to track how prospects are doing from the Prospects tab inside the cadence. Prospects can have different statuses for a cadence.
In Cadence - Prospects who are actively in the cadence and haven't replied, bounced, unsubscribed, or manually stopped by you
Completed without reply - Prospects who have completed all steps in the cadence without having replied, bounced, or unsubscribed
Bounced - Prospects for whom you have received a bounce message indicating the email wasn't delivered
Replied - Prospects who have replied to an email sent as part of the cadence
Replied stopped - cadence stopped for prospects who belong to the same domain as a prospect who replied (this is part of a safety setting in Settings -> Email)
Manually stopped - prospects for whom the cadence was manually stopped by you. The cadence can be resumed for these prospects at any time.
Auto-reply stopped - prospects for whom the cadence was stopped due to an auto-reply. The cadence can be resumed for these prospects at any time.
Unsubscribed - prospects who have opted out of an email from the cadence. They will not receive any follow up emails nor will you be able to add them to a new cadence.
