A Birthday Letter Worth Opening
Not a card. Not a text. A sealed letter they break open on their birthday — because some words deserve a ritual.
More meaningful than a card. Completely free.
Birthday texts get lost. Cards get recycled. But a sealed letter with a wax-seal ritual? That becomes a memory. Create a free birthday letter on OpenWhen, protect it with a question only the birthday person can answer, and share the link. When they open it, they break the seal and discover your words — making their birthday feel truly special.

Frequently Asked Questions

An Open When birthday letter is interactive — the recipient must answer a personal question and break a wax seal to read it. This creates a moment of anticipation and discovery that a regular card can't match. Plus, it's free.
Can I send a birthday letter to someone far away?
