If you want your form to use the same e-mail templates as another form, you can import templates.
To import e-mail templates:
If the form is not already open for editing, open it, as described in Opening a form for editing.
Click the “Set up completion messages” link. The system displays a screen with the heading Completion Messages.
Click “Import the ‘Completion Messages’ from another form” link. The system displays a screen with the heading Import Settings. This screen lists every form from which you could import e-mail templates.
Use the checkboxes at the left to select the form whose e-mail templates you want to import.
Click Import Selected.
