# 3. Configuration

As soon as you have created a new form of the CMS extension, a new trigger is automatically provided in the Flow Builder. To activate the confirmation email, you must first create a new flow in the Flow Builder. You can then select the trigger of the form and select "Send email" as the action. In the action settings, you can then select the option "Form confirmation" under "Recipient". This will send the email to the address specified by the sender in the form. It is important that there is a field in the form with the internal name "email", as the confirmation email will then be sent to the address entered in this field.

You can choose any template as an email template. If you want to refer to the data sent by the sender in the template, you can use the same variables that are available in the template for the email to the shop owner. You can copy these from the email template with the type "Custom Form" that was created by the CMS extension.

**Attention:**

If you change the internal name of a form for which a flow has already been configured, you must then reconfigure the flow, as the triggers are based on the internal names of the forms and the old name is then still stored as the trigger of the flow. Such flows are then automatically deactivated as long as they have not been updated.
