Help Scout aims to provide a top help desk app which is customisable and personal. It seems to have been very successful, too, based on the top reviews this software has received. You can create multiple mailboxes for a single shared email account, which means separate departments can work together. Real-time collaboration runs smoothly with Help Scout. The app can assist for all business types and sizes and the UI is easy to navigate. Your data is safe with two-factor authentication for all subscription types, and it is certainly one of the cheapest of its sort on the web.
