It's easy user friendly platform which gives me all options with ease from one window so that I can manage my mails as well as attachments effectively.it has great support team who provide you guidance whenever required at no cost. it requires more space than expected but if u are having large data size then also its ok otherwise everything good just try this tool once n feel yourself happy abt performance. Email server backup can't done using zerospamp service. Its best software available over internet till now with no other alternatives like dropbox or google drive etc. Best part i love how fast they deliver what ever asked without any delay and have amazing customer services too. I like that it's easy enought anyone can set up! It does what you need - protects from spam messages as well (or not). No complaints at all so far; have been using since last year or two when they first launched their business model change/upgrade which didn't go over very smoothly with some users due mostly being unaware there were other options out here if needed.
