The main benefit I see is being able to provide my clients an opportunity where they can be one step ahead from what's happening around them without having any hassle or extra cost involved as well! It also gives me peace when it comes time do send out emails / newsletters because everything has been done beforehand by formation - so no worries there either!! Nothing really dislikes but i guess you could say if your not familiar enough how things work then maybe this would come off like something difficult which isn't necessarily bad since its easy once u get used too haha.
But just try using different methods first before going straight down route otherwise nothing will happen :).
