LettersLetter vs Rumble Rigs

Where they differ

Both are letters, art & prints, stickers and activities clubs. LettersLetter covers postcards on top of that; Rumble Rigs stays narrower.

On price there is effectively nothing in it — $11.99/mo against $11/mo, which works out within a dollar a month of each other. Price is not the deciding factor here.

Shipping is the one that rules a club out rather than in: LettersLetter ships to US and 23 other countries, Rumble Rigs to Not stated.

LettersLetter addresses the post to the child by name; Rumble Rigs does not. That sounds minor and it is the detail people mention most often — the envelope being visibly theirs is most of the appeal for a younger child.

What each one sends

LettersLetter

One envelope a month with an illustrated short story, a collectible postcard, a coloring page, a character sticker and a small surprise such as a mini game. The envelope is addressed to the child by name. Subscribe by the 15th to start in the same cycle.

Rumble Rigs

Built around a collectible card game about trucks, and unusually generous for the price. Every envelope has a hand-illustrated trading card with battle stats, a letter written from the rig's own perspective, a screen-free activity, an 11×17 blueprint poster with a playmat on the reverse, a die-cut sticker and a bonus paper activity. Ships on the 1st.

Which one to pick

We are not going to pretend there is a winner here — they are close enough to be on the same shortlist, which is why this page exists. What we would say is that the choice usually turns on the household rather than the club: how much adult time there is, whether the child reads independently yet, and whether you want post that asks something of them or post that simply arrives.

Read the full listings before deciding, and follow through to each club's own site — prices, terms and gift options are theirs to change and ours only to record.
