Turn an open-when idea into a digital letter that stays sealed until a date you choose. It is a simple option for long-distance friendships, relationships, celebrations, and future encouragement.
Write your letter freeOpen-when ideas that work with a date
Try “open on your birthday,” “open after graduation,” “open on our anniversary,” “open when the semester ends,” or “open one year from today.” A date-based prompt matches the way Secret Letter controls access.
Emotion-based prompts such as “open when you feel sad” cannot be detected by the website. For those, choose a date or send the link with clear instructions.
Write for the moment they will be in
Imagine where the reader may be when the letter opens. Give them context, reassurance, a shared memory, and something practical they can do after reading.
Avoid making promises about the future that you cannot control. A warm, honest message lasts better than a dramatic prediction.
Share the link thoughtfully
The URL is created immediately. You can send it now and tell the recipient to bookmark it, or keep it until you are ready to deliver it. The service does not automatically contact the recipient.
