I like that it syncs to my gmail account so all of them are in one place! It's not as complicated nor user friendly when creating new emails compared other programs out there but once you get used too its easy peasy!! Nothing really at this time i dislike about mail bird because they have great customer service which has helped me through many issues over these past few months using their product.
So far everything goes smoothly no problems encountered yet just some minor bugs here nthere nothing majorly bad. !
