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 and mail two letters of their own (postage stamps included).

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, no stamps to buy, 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, guided envelopes, real postage stamps
