I found a bug.
Hello! I just found a bug that allow you to read letters before they are delivered.
If you click in "read public letters" you will find a link like this:
https://www.futureme.org/letters/public/xxxxxx-a-letter-from-february-20th-2019
Now, if you go to you account and mark the traveling letter as "Public", and put your mouse cursor over your own email, you have the number of the letter. Then, if you change the public letter link to your own letter number with the deliver date, you can read the travelling message.
Something like this: https://www.futureme.org/letters/public/YYYYYYY-a-letter-from-JANUARY-30th-2025.
Sorry for my bad english, i just want to help and i hope you understand me.
