Proud of You Snail Mail Club

Proud of You is a letter subscription about personal growth, written for people who want to learn away from screens. Each month takes one topic, such as self-worth, imposter syndrome, burnout or self-doubt, and covers it with research, a lesson, journal prompts and practical tools. Every letter comes in a different colored envelope, sometimes with a bonus surprise, and subscribers can write back using the return address.

It costs $7 a month, plus $2 for international shipping, with prepaid six and twelve month options. Billing renews on the 10th; the site currently asks you to sign up before October 9th for the next letter.
