# Poptin Activity Trigger

Poptin Activity triggers fire based on how contacts interact with your Poptin popups and forms. 


1. Converted on Poptin - Triggers the automation when a contact converts on a specific Poptin popup or form (e.g., submits a lead form, signs up via a popup, or completes a popup goal).

* **Which poptin should trigger this flow when a contact converts on it?** *(required)* - Select the specific popup or form from the dropdown. The flow will fire whenever a contact converts on that poptin.

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

* **Re-trigger the flow for contacts that have been in this flow before** *(required)* - Defaults to **Every time**, meaning the flow will fire each time a contact converts on the selected poptin.

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

| **Note:** This trigger works great for sending a welcome email right after a contact signs up via a popup. See: [How to send a welcome email to new contacts →](https://poptin.ai/chat/PLACEHOLDER_USECASE_WELCOME_URL)
