If I could leave no stars I would. I've had the misfortune of using them for my business email account for a few months. It's frequently cut out altogether in the middle of projects, leaving me unable to contact clients- and not able to check my emails have been received. Likewise, sending email to myself from more reliable accounts sometimes arrive 4/5 hours later or just aren't picked up at all. Their support is very often offline, and the interface is as clunky and counter-intuitive as something you might have found in the late 90's. I'd strongly advise you not to use them for anything at all, let alone something you need to rely on!
