Tell Zip about your child. Mail arrives twice a month. They write back, and Zip remembers.
Share their name, age, address and favorite things.
A personal story, then another envelope with a letter and paper play. Two mail days a month.
Send a letter, drawing or scribble. Zip can weave it into future stories. Replies are optional.
A real envelope, addressed to your child, their name, not “current resident.” Inside:
Their name, favorites and real-life moments in a story, with a growing Crew Member File.
Meet mailbox friends like Cooper the coupon, Penny the detective and Pablo the postcard.
Their favorite things to color, plus games, hunts and mazes matched to their age.
Another letter, coloring and a paper game keep the friendship going.
The math: 12 big letters + 12 note-and-play envelopes = 24 mail moments a year, all part of Season 1, “The Mailbox Mystery,” a year-long mystery your child's own replies help solve →
Mail a drawing or share it in the parent portal. Their dinosaur might join the story. Their idea might become a clue.
That's the difference between getting mail and having a pen pal who remembers you.
Read-aloud stories or deeper mysteries, written for their reading level.
Short read-aloud stories, big pictures and simple coloring.
Easy reading, drawing and playful activities with a grown-up.
Richer stories and guided discoveries. The characters explain the clues.
Longer letters and optional independent mystery solving.
Same friend, bigger adventures. The reading level grows with your child.
