I signed up and switched all my business emails to this, and they suddenly blocked my account saying there was unusual activity on it (absolute rubbish), when I emailed support I was just told it would remain blocked but they can't give me a reason! Thank goodness I only had it a couple of days, but I still can't access emails I will have received in that time. Wish I'd seen these reviews before I signed up, do NOT use them what a huge waste of my time, fuming! Stay away!
