If you wish to receive a VINCE notification whenever another a different specific vendor receives a VINCE notification, you should contact the other vendor (outside of VINCE) and ask that vendor's VINCE Admin to add your chosen email address to their vendor contact information. Likewise, if you wish for another vendor to receive a VINCE notification whenever you receive a VINCE notification, then you should add an email address to your VINCE contact list that will reach that other vendor.
