You can receive an alert email when a form is submitted. This feature is only available with the pro or multi account plans.
Here's how to set up an alert step by step:
Create a tag first on the list of tags page. We'll use an example "Partner".
Then, in the form editor add this tag as a hidden field like this:
Add a new field
Select tag
Select hidden field
Select the tag
Click add
The tag is added to the form as a hidden field
Save the form and exit the form editor.

Next, on the alerts page create a new alert using the tag for the condition to trigger the alert.

Finally, fill out the form to test / ensure you receive the alert.
