Open-when letter ideas

An open-when letter is a note for a moment that hasn't happened yet. Seal it now, and it opens on their phone on the day you pick.

For a partner

For long distance

For a best friend

How to send them

Seal one capsule for each moment and give each its own opening date, from 1 hour to 5 years away. Your friend sees a countdown and can lock in a guess about what it says, and on the day it opens with a reveal.

Questions

What is an open-when letter?

A short note to open at a specific moment, like "open when you miss me" or "open when you get the job". With Tellater each one is sealed until a date you pick, then it opens on their phone.

Can I send several at once?

Yes. Seal one capsule per moment and give each its own date, so they arrive one by one.

Will they know it's from me?

Yes. Tellater isn't anonymous: your name is on the envelope with a tick and the last 4 digits of your verified number.
