I like that it's easy for me as an individual user (not admin)to log into my account from any computer or mobile device without having internet access at all times! It would be great if you could have more than one subdomain per site so we can use different email addresses within our organization but this seems not possible yet? Great product overall though - definitely recommend trying out their service before making your decision about which provider will best fit what needs/requirements are important to us right now.- Email address management; ability track changes made by multiple people across sites using same domain names.
