# Trigger Sequence

> Enroll a contact into a drip sequence from another workflow.

## What is this?

**Trigger Sequence** enrolls a contact into a [sequence](/workspace/automation/steps/sequences) — a series of timed messages, like a drip campaign — from within another workflow. It's the trigger used on the sequence's own workflow, so that other automations can hand a contact off to it with a **Trigger Sequence** step.

## How to use it

<Steps>
  <Step title="Build the sequence workflow">
    Create a workflow with **Trigger Sequence** as its **Trigger Type**, then add **Sequence Drip** steps for each timed message. See [Sequences](/workspace/automation/steps/sequences).
  </Step>

  <Step title="Enroll contacts from another flow">
    In any other workflow, add a **Trigger Sequence** step and point it at this sequence — for example after a lead is qualified.
  </Step>

  <Step title="Add an exit condition">
    Use a **Condition Logic** step in the sequence so a contact who replies or converts stops receiving the rest of the drip.
  </Step>

  <Step title="Test, then activate">
    Enroll a test contact and confirm the timing and content, then activate both workflows — see [Manage Live Flows](/workspace/automation/manage-live-flows).
  </Step>
</Steps>

### Tips

* **One sequence, one purpose.** A re-engagement drip and an onboarding drip work better as two separate sequences than one long branching one.
* **Don't double-enroll.** Check whether a contact is already in the sequence before enrolling them again.

## Troubleshooting / Technical Notes

* **The sequence never starts.** Confirm both the sequence workflow and the workflow calling **Trigger Sequence** are **Active**.
* **A contact keeps receiving messages after replying.** Add or fix the exit condition in the sequence.
