TrustMRR's newsletter just reached 10K readers 🎉 100% of the content is written by AI. I send a bunch of data to a cheap GPT model and ask it to write the newsletter in a specific structure. It generates the HTML, which I copy/paste into Beehiiv. Before sending, I do one quick review, just in case. It has ~40% open rate and ~10% CTR. 100% of the sign-ups come from the pop-up at the bottom-right of the site. It’s shown to all visitors after a 900px vertical scroll.
