Auto-Unenroll
Auto-unenroll is Automatoir's built-in safeguard against sending follow-ups to prospects who have already responded. When a reply is detected, the prospect is automatically removed from the sequence and no further steps are sent.

How Reply Detection Works
Automatoir monitors your connected inbox for incoming messages via the Nylas webhook. Each sequence step is sent as a reply in the same Gmail thread — step 1 stores the thread ID, and every follow-up is threaded into it. When a new email arrives, Automatoir matches the sender's email and the thread against active enrollments.
If a match is found, Automatoir marks the enrollment as replied and triggers the unenrollment process. This happens automatically — you do not need to take any action.
Paused Enrollments and Retry
If a step fails to send — because of a temporary Nylas outage, a transient Gmail error, or a missing draft — the enrollment is marked as paused with an error message. A badge appears on the sequence detail view showing how many enrollments are paused, and a sidebar count surfaces it globally so you notice quickly.
Open the paused enrollment to see the specific error and click Retry to reset its next-send timer and attempt the step again. No data is lost — the enrollment resumes exactly where it left off.

What Triggers Unenrollment
The following events cause a prospect to be automatically unenrolled:
- Direct reply — The prospect replies to any email in the sequence thread. This is the most common trigger.
- Out-of-office reply — Auto-replies are detected and treated as replies. Automatoir pauses the sequence rather than continuing to send into an unmonitored inbox.
- Bounce — If an email bounces (invalid address, full mailbox), the enrollment is marked as bounced and no further steps are sent.
Manual Unenroll
You can also unenroll a prospect manually at any time. Open the sequence detail view, find the prospect in the enrollment list, and click Unenroll. Manual unenrollment is useful when:
- You've had an offline conversation and further emails are unnecessary
- The prospect has asked to be removed through a different channel
- You realize the prospect is not a good fit and want to stop outreach

What Happens to Remaining Steps
When a prospect is unenrolled — whether automatically or manually — all remaining steps are cancelled immediately:
- Any scheduled but unsent steps are removed from the send queue
- Any pending review drafts for this prospect are dismissed
- The enrollment status changes to unenrolled (manual) or replied (automatic)
- Historical data for steps that were already sent is preserved for analytics
Unenrollment is final for that enrollment. If you want to re-engage the prospect later, you can enroll them in a different sequence or re-enroll them in the same sequence, which creates a new enrollment record.
