Start a card for a birthday, a wedding, a new baby, or a first day at a new job. Share the link. Every note becomes its own real postcard, mailed straight to their door — no group-chat screenshots, no group-chat junk.
Name the person and the occasion. You'll get a link to share with everyone who wants in.
Each person opens the link on their own phone and writes a short message. It becomes one real postcard.
Every postcard ships on its own, so their mailbox fills up over the week instead of one envelope at once.
