The most useful thing about this software was that I could make my customers aware through text messages when they had an unread message in Gmail without having to log into gmail myself! It also allowed me access from any computer so if someone wanted help at work we were able solve whatever issue he/she may have right away instead waiting until after hours where other methods would be slow due lack off employees available during regular business times!! Sometimes you get stuck trying figure out how something works but luckily there are plenty tutorials online which helps alot.
If your looking fo ways tg keep up wth competition use net core mail api its great i used all 3 services before switching over using google one last time then choosing them again cuz now im totally satisfied no problems here not even complaints only suggestions. !
