Give them a reason to run to the letterbox
Every month, Max & McKenzie post a real adventure letter to your child — a story, activities, a recipe, a science experiment and more. Every child starts at Chapter 1: Cairo, and travels the world one letter at a time.

The Mailbox Club is a series, not a magazine. Every child starts at Chapter 1 — no one joins mid-story. Max & McKenzie travel the world together, and your child travels with them from the very beginning.

Where should we send it?
Time for pure, focused magic
No screen. No app. Just their name on a real envelope, and a whole world inside it.
The arrival
A bright, themed envelope lands in the post with your child's name on it. They race to open it.
The discovery
Out spills the letter, stickers, paper characters, a recipe, an experiment and puzzles.
The adventure
The month unfolds — they cook, build, decode and listen, then beg for the next chapter.
We make every letter for our four kids — and yours
We're Saul and Helen — a New Zealand family who've lived and travelled all over the world, from the Pacific islands to South Africa, Ireland and Europe. We homeschool our four children, and The Mailbox Club is the curious, world-sized childhood we want for them. Every chapter is road-tested by our own kids before it's posted to yours.
What families told us
We're a young company with a growing family of subscribers. Every word below is from a real family who read a real letter.
We loved our adventure to Egypt and are looking forward to flying off somewhere else soon! The children particularly enjoyed the map of Cairo and felt very knowledgeable!
Full of hands-on learning and discovery. The activities kept them engaged and busy for hours. Highly recommended!
My son loves Max & McKenzie's letters — he asked for the letter as his bedtime story for 6 days in a row. He absolutely loves the Podcast as well.
Honest by design: we'd rather show you a handful of real reactions than a wall of reviews we can't stand behind.
