Let's pretend you got mail.
This app is a tool for receiving a genuine fake email.
From fictitious address, from future or past,
you can pretend that received any email.
For example, you can receive
emails from your (fake) boyfriend / girlfriend,
emails of your (fake) work that will come in a very good timing,
and your (true) encouragement emails (however, please write on your own).
Depending on your imagination, you can create a variety of production.
In joke use, in practical use? please try it.

At first, you have to make new mail account for FakeMail.
If it's difficult, setting example is my website (https://fakemail.null-i.net).
