Speak to that exact moment
A letter for a sad day shouldn't be a general love letter. Imagine them reading it in that moment and write to that version of them.
Open when letters
Open when letters: 50 ideas, and how to send them when you're far apart.
Open when letters are sealed notes for specific moments — “open when you miss me”, “open when you can't sleep”. They're one of the best long-distance relationship gifts because they keep working long after you've sent them. Here are 50 ideas and what to write inside.

What to write inside an open when letter
Keep each one short
A few honest paragraphs, a memory, and one thing to do (call me, put on our song, look at this photo). Short letters get reread.
Add something they can feel
On paper: a photo or a pressed flower. Digitally: put your photos and your song around the envelopes, in the same private page.
Go digital when you're far apart
Paper letters take weeks to cross borders and only exist in one place. A digital stack of open when letters arrives instantly and is always on their phone.

Frequently asked questions
What are open when letters?
Open when letters are a set of sealed letters, each labelled with a moment to open it — when you miss me, when you're sad, on your birthday. They're popular in long-distance relationships because they offer comfort at the exact time it's needed.
How many open when letters should I write?
Between 6 and 12 is ideal. Cover a few hard moments (sad, can't sleep, missing me), a few happy ones (good news, celebrating) and one or two special dates.
What should I write in an open when you miss me letter?
Remind them of a specific memory together, tell them what you'd be doing if you were there right now, and give them something to do: listen to your song, look at a photo, or call you. End with the next time you'll see each other.
Can I make digital open when letters?
Yes. A Lovelet can contain an “Open When…” stack of envelopes, each with its own letter, alongside your photos and music, sent as one private link. It's ideal for long-distance couples since nothing needs to be posted.
