SantaInbox by Floo is a magical email-based experience powered by Postmark and AI that turns every child’s letter to Santa—written a heartwarming, personalized reply… complete with a storybook-style illustration and optional print-on-demand delivery 🎅📬
💡 The Idea
Every year, kids around the world write letters to Santa…
What if an AI, powered by Postmark's email parsing, could read those letters and send magical replies in seconds?
With SantaInbox, parents and teachers can:
- send a child’s message to
santa@santafloo.com - and receive:
- 🎅 a personalized letter from Santa
- 🖼️ a custom illustration matching the child’s wishes
- 📦 an optional print-ready version (for physical delivery)
No app. No signup. Just… ✉️ email magic.
📬 Powered by Postmark Inbound Email Parsing
