Sunny the Mail Snail vs The Adventure Letters

Where they differ

Both are letters, stickers and activities clubs. The Adventure Letters also covers travel; Sunny the Mail Snail stays narrower.

The Adventure Letters is the cheaper of the two — $12.99/mo against $58 for 3 months, roughly 33% less on a monthly basis. Whether that gap means anything depends on what turns up: the dearer club is not automatically sending more, and on a gift the up-front total matters more than the monthly figure.

They arrive on different rhythms. Sunny the Mail Snail comes weekly; The Adventure Letters comes twice a month. More frequent post is not automatically better — it is more to keep up with, and for some children the wait is part of it.

The age ranges differ too: Sunny the Mail Snail is pitched at ages 3–8, The Adventure Letters at ages 8–13. Match the reading level rather than the birthday — a child who cannot yet read the letter alone needs an adult in the loop either way.

What each one sends

Sunny the Mail Snail

A snail character named Sunny writes four to five personalized letters a month, roughly one a week. Envelopes hold animal trading cards, secret code cards, stickers, temporary tattoos and bookmarks. A plush Sunny comes with the six- and twelve-month plans.

The Adventure Letters

Two letters a month, mailed the second and fourth Friday, telling a continuing story about US geography and travel. Each envelope includes stickers, scrapbook pages, conversation cards and the occasional small gift. US shipping is free; there is no international option.

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.
