Example
You're reading this on the train, probably. I hope you finally called Dad more than once a month. If you didn't, call him today.
— Me, at 29
For yourself
You won't remember what today felt like. Write it down, seal it, and let it find you later. Kept Letter delivers it by email on the morning you choose.
As long or short as you like. Add photos or a voice note if you want to hear yourself.
Next birthday, New Year's Day, or 5, 10 or 25 years from now.
It arrives by email on that morning. Until then, not even you can read it.
Pick two or three. A few honest lines beat a long letter nobody finishes.
