You may want a field in your mobile form that only allows a valid email response. Using a Short Text field you can require an email address (ie: XXX@XXX.com). The email entered in this field will automatically be pulled into the Email Recipients list at the end of the form. However, the mobile user can delete this email from the list unless Always email submissions to this address is checked.
Note: At this time, email style fields are only available in the Advanced Form Builder. If you would like to utilize this functionality on a form built in them Builder BETA, roll back to the AFB using the hyperlink at the top of the screen. However, once you leave the Builder BETA for this form you cannot return for this form.
Creating an Email Field
1. Find an existing short text field for an email or add a short text field and select the field to open Field Settings in the left panel.
2. Expand the Style drop down and select Email.
3. Save and Publish to see it in action.
Now if the mobile user attempts to enter anything other than a valid email address in the field, an error will popup notifying that a valid email address is required.
Always Email Submissions to this Address
You also have the option to Always email submissions to this address. This will ignore what the admin has configured in the Email Options form setting. Even if the form has it's email options set to either "Cannot email the PDF to anyone" or "Can email the PDF to themselves only," this field will still send the PDF to the email captured in the field. The mobile user can also not see the email listed on the Complete Submission page under Email Submission and therefore will not be able to delete it either.
Please Note: The size limit for emailing a PDF Submission is 25 MB.
