Episode notes
Hobby Artside Hustle Turned Mail Story Business
- Michael and Hanny started The Flower Letters by mailing story-chapter letters after Hanny sold paintings quickly on Instagram and suggested sending physical letters to build an audience.
- They launched in August 2020, priced $12/month for two letters, and reached 33 initial signups from organic posts and friends.
Prioritize Email Acquisition First
- Build an email list as early priority because paid channels can fail; email drove up to ~40% of their revenue.
- Acquire emails on-site with a discount funnel and use email campaigns for wins and product launches.
Prepaid Subscriptions Improve LTV And Churn
- Prepaid up-front purchases drastically improve unit economics and retention for serialized stories.
- Their prepaid option ($100 for a year ~ $8.50/mo) became the main growth lever and reduces churn risk because buyers commit to the full story.
