Little envelopes for the big moments. Open the letters your family wrote for you, one at a time, right on your phone. Someone who loves you made you a box of “Open when…” letters. Whenvelope is where you open it. Parents, grandparents and the people cheering you on write letters for the moments ahead: when you miss home, when you ace a test, when you can’t sleep, when you just need a laugh. Each one waits in its own sealed envelope until you need it. OPEN THE ONE THAT FITS Pick the envelope that matches how you feel right now. Inside is a letter from home, plus photos, a video message, a song or a gift card if they tucked one in. ONE AT A TIME Whoever made your box picks the pace, like one a day or one a week, so the letters last. Some envelopes skip the wait, so “Open when you really need to talk” is always there. Others are saved for a certain day, like your birthday. KNOW WHEN THERE’S MORE Turn on notifications to hear when new envelopes arrive and when you can open the next one. SEND SOMETHING BACK Film yourself opening your box, or record a quick thank-you, and send the video to whoever made it. FOR EVERY BIG STEP College, moving out, a wedding, a first baby, a deployment: there’s a box for each. GOT A BOX? Tap the link you were sent and it opens right in the app. No account needed. MAKING A BOX? Write the letters, set the timer and design the box at whenvelope.com.
