Secret Letter guide
Open When Letter Ideas for Every Kind of Moment
The strongest open-when prompts point to a recognizable moment and offer something the reader will need then: comfort, perspective, celebration, or a shared memory.
Date-based ideas
Open on your birthday. Open after your first month at university. Open on New Year's morning. Open when the project ends. Open one year after we said goodbye.
Relationship ideas
Open on our anniversary. Open after our next big adventure. Open when distance feels especially long. Open before an important conversation.
Encouragement ideas
Open before your exam. Open after a difficult week. Open when you need proof that someone believes in you. Open when you forget how much progress you have made.
Match the tool to the prompt
Secret Letter unlocks by date and time, not by emotion or event detection. Choose a date that represents the intended moment and explain the prompt when you share the link.
