Carry Echo - Write a letter today. It arrives years from now.

Hi Product Hunt 👋 I built Carry Echo for the things that don't fit in a text: a letter to your daughter for her 18th, to your partner for your 10th anniversary, to yourself in five years. You write on a real sheet of paper, place photos and voice notes by hand, and pick the day. We keep it sealed until then, and the person opens it from an email with no account and no app. Text letters are free, with no limit. Paid plans add photos, voice and video. If you ever cancel, letters you've already scheduled still arrive. That promise mattered more to me than anything else in the product. I'd love to hear what you'd write first, and who it's for.
