Write a love note or birthday letter, add photos and a voice note if you like, and send it in an envelope they open from one link. No app, no Lav Note turns a birthday wish, an apology or an anniversary message into something worth keeping. Write a letter, add photos with captions and an optional voice note, then send it as an envelope your person opens from one link. No app, no account, nothing to install. Pick a template for birthdays, anniversaries, long distance, saying sorry and more.
