Designing a Keepsake-First Digital Letter Experience

Most messaging products optimize for speed. Garden Letters started with the opposite question: what if sending a digital note felt more like giving a small gift?

The product flow is built around four deliberate choices:

1. Composition: floral paper, fonts, and decorations make the writing surface feel personal.
2. Mood: an optional watercolor background is generated from the letter’s mood.
3. Delivery: recipients open a sealed-envelope experience, with optional preset music.
4. Sharing: a letter can be published publicly or shared privately with a code.

A few product constraints shape the experience:

• Composing and previewing are free.
• Publishing costs $4.99 USD per letter as a one-time payment. That unlocks five successful AI background generations, sharing, long-term storage, and an HD image download with a watermark.
• Private letters do not appear in the public garden and can be protected with a share code.

The broader product lesson is simple: if the emotional intent matters, it should be visible in the interface and in the privacy model. A “send” action can be technically successful while still feeling wrong if the recipient experience is treated as an afterthought.
