# Campaign Activity Trigger

Campaign Activity triggers fire based on how contacts engage with your email campaigns you've sent..

**Available Triggers**

* Opens Email

* Clicks Email

1. **Opens Email** - Triggers the automation when a contact opens a specific email campaign.

* **Which email should trigger this automation?** - Select the campaign from the dropdown. The flow will fire when a contact opens that specific email.

* **Who should enter this automation?** - Choose which contacts are eligible to enter. You can select All Contacts, All Subscribers, or a specific segment, with an optional filter.

* **Re-trigger the flow for contacts that have been in this flow before** - Defaults to **Every time**, meaning the flow will fire each time the contact opens the selected email.

Once configured, click **Select Trigger** to save.
