I like that it has an option to send emails from my computer or mobile phone, so if I am not at home I can still send out messages without having to use my office email account. Sometimes when you are sending large files they get stuck in the queue which is very frustrating! Make sure that you have enough storage space for all of your attachments. It's really easy to set up and there aren't any extra fees once you've got everything set up correctly. We were able to easily communicate with our clients using this service as we could do it anywhere, anytime.
