A very open challenge for creative people
Challenge brief
There are now many ways to create newsletters.
You can ask OpenClaw to send you an email every morning with specific information, or build a simple project with a cron job that uses LLMs to generate a Newsletter automatically.
Today's Viberacing challenge:
This challenge is sponsored by Zavu.dev. We'd love for you to send your emails using Zavu.dev — here's the Email Setup Guide: https://docs.zavu.dev/guides/email/setup (you can send via sandbox, or configure your own domain).
The winner will be whoever builds the most impressive, useful, interesting, sophisticated, and valuable newsletter — and the jury will be all of you, voting anonymously.
