Before technology evolved, people would use ordinary paper letters to convey something. But as technology evolves, more and more people use it, and instead, people will use an email to do that. Every day, we receive many emails coming from different sources, such as Google, 365 Offical, and many other things. So users will need an application to manage all that and make things a lot more convenient. I would suggest to the player an app, which is Aqua Mail – an app that manages everything. So if the player wants to make things a lot easier, this app is indispensable.
