# Pausing, editing, or canceling a sequence

You sent a sequence and something's off — wrong template, wrong list, wrong cadence. Or worse, you're watching a lead get the same email three times in a row. Here's how to take control.

## Quick reference

| What you want to do                                | What to do                                                       |
| -------------------------------------------------- | ---------------------------------------------------------------- |
| Stop the whole sequence from sending anything more | **Pause** the sequence (toggle it from Active to Paused)         |
| Stop sending to one specific lead                  | **Cancel** that lead's enrollment from the sequence details page |
| Tweak the template or timing for future sends      | Edit the sequence (pause first, edit, resume)                    |
| Permanently remove the sequence                    | **Delete** the sequence                                          |
| Re-send to leads who were canceled or completed    | Use **Re-enroll** from the sequence details page                 |

## Pause a sequence

Pausing is the safest "stop everything" button. Pause when you're not sure exactly what's wrong but you want sends to halt while you investigate.

1. Go to **Pulse → Sequences** in the Hub.
2. Find your sequence in the list. Click the Active/Paused toggle to flip it to Paused.

When a sequence is paused:

* **No new leads enroll**, even if they match the trigger.
* **Already-enrolled leads stop progressing.** Their pending steps are held — not sent, not skipped, not lost.
* **Already-sent emails stay sent.** Pausing can't recall something that's already gone out.

When you resume, pending steps pick up from where they left off. If a step's scheduled date passed during the pause, the step skips forward to the next valid time (or honors its end-date setting, if one is configured).

> **If you need to stop sends right now and aren't sure what else is happening:** pause first, diagnose second. You can always resume.

## Cancel one lead's enrollment

If only one lead (or a small group) is affected — wrong person enrolled, lead asked to be removed, etc. — cancel that enrollment without pausing the whole sequence.

1. Open the sequence in **Pulse → Sequences**.
2. Go to the **Enrollments** view.
3. Find the lead. Use the row action to **Cancel** their enrollment.

The enrollment status flips to CANCELLED. No more sends go to that lead from this sequence. The lead can be re-enrolled later if needed.

## Edit a live sequence

You can edit a sequence while it's active, but it's safer to pause first if the change is non-trivial.

**Safe edits without pausing:**

* Renaming the sequence
* Editing copy on a step that hasn't been scheduled yet (no leads at that step)

**Edits that benefit from pausing first:**

* Changing the timing on a step
* Reordering or deleting steps
* Adding new steps
* Changing the trigger

When you change a step's content, **only sends that haven't been queued yet pick up the new content.** Anything already sent stays sent. Anything that was already scheduled to send within the next few minutes may have been queued with the old content — pause first if you need certainty.

After editing, resume the sequence.

## Delete a sequence

Deleting removes the sequence permanently. Anything that hasn't sent yet won't send. Existing enrollment records remain for audit but no further activity happens against the sequence.

> **Prefer pausing to deleting** unless you're certain you won't want to resume. Pausing keeps your edit history and lets you reactivate the same sequence later. Deletion is irreversible.

## Emergency: a sequence is sending too many emails

If you're seeing a lead receive the same email multiple times, or sends going out faster than configured:

1. **Pause the sequence immediately** — first action, before investigating.
2. Open the **Enrollments** view to see who got what. Cancel the worst-affected enrollments.
3. Check the **Triggers** — multiple overlapping triggers shouldn't cause duplicate sends (Mobly deduplicates enrollments), but a misconfigured Tag trigger could be re-enrolling leads each time a tag is reapplied.
4. Contact your CSM with the sequence name, the affected lead(s), and what you observed. Mobly's team can audit the send history server-side and confirm what actually went out.

## Re-enroll leads

You may want to send a sequence to leads who already completed it, were canceled, or were marked ineligible — for example, after editing the sequence content.

1. From the sequence details page, use the **Re-enroll** action.
2. Optionally scope it to a specific list of leads, or re-enroll everyone who isn't currently active.

Re-enrolled leads start the sequence from step 1.
