These terms are effective August 2, 2026. Checkout is available only to adults who accept them.
The membership
Petra's Mail Club is a monthly physical-mail subscription for children. Each Mail Drop may include a letter from Petra, an original-art postcard, Greek facts and simple words, stickers, and an activity, game, or creative challenge. Contents vary each month.
Price and recurring billing
The price is $12.99 USD per month, with international standard shipping included. The adult subscriber authorizes Stripe to charge the payment method each billing period until canceled. The price and renewal frequency shown at checkout control if they differ from this page.
Who can subscribe
A parent, legal guardian, or other adult able to enter a purchase agreement must place and manage the order. The subscriber must provide a complete, deliverable shipping address. One subscription corresponds to one monthly Mail Drop.
Mailing schedule
Sign-ups close on the 1st of each month and the Mail Drop is sent from Greece on the 5th. Typical delivery is 2 to 3 weeks, but postal timing is not guaranteed and regular snail mail does not include tracking.
Address changes
Subscribers are responsible for keeping the recipient name and shipping address current in the Stripe customer portal. A late change may apply only to future Mail Drops.
Cancellation and payment issues
Subscribers may cancel anytime through the Stripe customer portal. Cancellation takes effect at the end of the current paid period. If payment fails, the related Mail Drop may be held.
Changes to the club
Petra's Mail Club may update future themes, paper contents, schedules, or the service. Material changes to price or recurring billing will be communicated where required.
Archive content
Writing, illustrations, photography, and site content remain protected by applicable intellectual property rights. Purchasing a letter does not grant a right to reproduce or sell its contents.
