47 emails that changed how I think about email design.

Why I made this

I'm George Hartley. I spent a decade building email tools. My last company, SmartrMail, had 12,000 customers and sent 6 billion emails before it was acquired in 2022. I've seen more email than most people will in a lifetime. Most of it is forgettable.

Now I'm building nitrosend, a full-stack email platform designed for AI. The goal is simple: you should be able to prompt Claude or Codex and get a beautifully designed email back. Not a template. Not slop. Something with real taste.

The problem is that AI generates from averages, and the average email is mediocre. The only fix is to show it what great looks like. So I started collecting. 47 emails later, it became something worth open-sourcing.

This collection is also part of the Email Marketing Bible, a 65,000-word guide built from 908 sources and 44 industry experts. If you want to go deeper on strategy, segmentation, deliverability, and the rest of it, start there.

I hope this is useful. I hope it raises the bar for what email can look like. And if it helps you send something that makes one person stop scrolling, it was worth it.
