How to avoid sending extra emails for multi-page form

I have a form that is actually a suite of 4 forms.

After three of the four sections is submitted, an email is generated and sent to a staff member with the details of the form. The problem I'm having is that if someone submits one of the forms and decides to come back at another time to fill out the rest of the forms, conditional emails for the forms they previously submitted are being sent again when they click to Save and Close their form.

Is it possible to submit an email only once? Can you think of another work around?

Thanks!

So you mean that you wish to halt further email notifications if your form(s) are returned and continued at a later point?

I see your form has the 4 sections on it and I think you meant those are the 4 form (parts) to be continued later if needed.

Unfortunately there's not really a way around that because each time the form is updated or continued and then submitted again it is sent to you as an "Edited|Updated" Submission and that is also reflected to show the edited updated information which shows this in the Notification as well to inform you that it was Edited. This is currently how the form is designed to handle it. 

An alternative suggestion would be to Integrate it with Google Spreadsheets as an example which would show each submit as a new entry in the spreadsheet regardless of what was filled in before but that might get a bit confusing.

Actually, something I just remembered which might seem a bit tedious but as a work around for the above issue that you have you could make it out of 4 forms embedded onto one master form. It would basically send you an email notification only for the individual sections since they would be separate if filled out separately. 

This suggestion would basically work very similarly to a multi-payment form but it would be your form sections instead of payment integrations that are embedded with the iframe embed widget.

The only downside to this workaround that your data would be scattered across 4 different forms which might be a bit of a hassle for some.

I appreciate your suggestions. I think I might go with a Staff Only radio button question to toggle that on or off. Or, just deal with all of the emails.

Thanks again.
