Heartpost Letter Club

More than just happy mail. A reason to send it.

Pip’s First Flight box laid out — the SPECIAL DELIVERY envelope, a white feather keepsake, a wax seal, Pip’s trading card, the story, a coloring page, stickers, and real stamps.

Every month, Happy Mail Bundle arrives addressed to your child — a personalized letter from Pip, a story to follow, fun collectables, and EVERYTHING they need to write two letters of their own — with the option to add postage stamps at checkout, so they're ready to mail right away.

Meet Pip

Pip is a newly certified carrier pigeon on his very first mail route. He’s kind, a little clumsy, and endlessly curious - and he’s learning as he goes, right alongside your child.

Pip isn’t a mascot. He’s a friend who writes real letters, and helps deliver theirs. The magic isn’t in getting this happy mail — it’s the moment after it’s opened, when your child picks up a pen and writes letters of their own.

What the club is all about

Most kids’ mail subscriptions are about receiving. This one is built around sending. Each month follows one simple loop:

Steps 1-3, receive, read, write

Steps 4-6, seal, stamp, mail

It’s a monthly snail mail kit that gently turns your child into a pen pal — no printing, nothing extra for a parent to do.

What arrives each month

  • A new illustrated story chapter
  • A personal letter from Pip, with their letter writing missions for the month
  • A tiny keepsake and collectible card
  • Fun themed sticker sheet
  • Everything to send two real letters: stationery and guided envelopes (add postage stamps at checkout if you'd like them included)
  • OPTIONAL Adventure Guide

More than one letter writer?

Brothers and sisters can join in too. Add up to four children to the same monthly bundle for $5 per additional child, and everyone gets their own stationery, envelopes, activity page, sticker sheet, and wax seal. The story, Pip’s letter, the monthly keepsake, and the collectable card are shared — one read-aloud, one growing collection, and one envelope in the mailbox.

Go deeper with the Adventure Guide

Each month's Adventure Guide is inspired by that month's story — a simple 5-step framework (Read Together, Explore, Create, Connect, Share) that turns the story into real conversation, a guided physical activity, a hands-on project, and a reason to write a letter about it. Every guide includes age-tiered activities for ages 4–6, 7–10, and 11+, so the whole family can join in together, and it flexes from a quick 15-minute activity to a deeper 45-minute homeschool lesson. One guide covers the whole family. It’s a nice bonus for any family who wants to dive deeper into the story, theme, and experience of the month, and especially helpful for homeschool families looking to layer some enrichment onto their current learning calendar. It's an optional add-on for $5/month.
