ATLAS FormBuilder - Test Mode explained
In FormBuilder you have the option of running your form in test mode. When a form is in test mode, all generated emails will be sent only to specified testing addresses rather than their original recipients.
To find(and add) your testing email address, click the gear on the far right side of your form group and select "Edit form Group." You will need the permission level of Unit Administrator in ATLAS FormBuilder to edit the form group settings, including the testing email address.
