Redundant Confirmation E-mail

We have a single signer form provided via a widget.

Once the user completes/signs the form, we always end up with 2 copies in our inbox.

The first has the subject line "User_X has signed Form_1."  The PDF attachment consists of just the signed form.

The second e-mail we receive on our end has the subject line "Form_1 between Company_Z and User_X is Signed and Filed!"  The PDF attachment consists of the signed form with the extra Cloud history page.

We really only need the first e-mail with the signed form, not the redundant confirmation that it was completed.  Is there any way to disable that second e-mail getting sent to our inbox?

Thank you
