ZooBuh prides itself on being able to offer a safe alternative to other email accounts. There are many companies that offer these accounts for free, but most--if not all don't have any parental controls or filtering specifically for kids. Furthermore, these companies get their revenue mostly from advertising. ZooBuh has no advertising inside the child's login area because the content must be controlled to keep it safe. ZooBuh charges a very minimal price to offset the cost of offering this service. We feel it's a small price to pay for safety and peace of mind.
