Review on Email YoYo by Robert Tirona

I like that it's easy to use, you don't have to do anything complicated to get started using it. It also looks nice from our side in terms of UI/UX. Not much to dislike right now since they are still under development, but we've been testing their beta version for some time now without any issues found so far. We were looking at other solutions before this one, but I can say with confidence that they're great! They solved all our problems regarding blacklisting domains as well as whitelisting those who should be able to transact business emails through our service provider's inboxes.
