Have you tested this in marketing emails? that seems to be the profitable marketplace. Even if you can prove 5% increase in roi that's worth a lot to a lot of people!

There are some interesting studies showing short emails perform better but we haven't found that to be true it seems the message is the biggest factor. Some way to improve the message is even more valuable but also likely a much harder ML task

The original inspiration and example featured on the website was from a blog post on cold "welcome" email copy: https://www.gkogan.co/blog/increase-reply-rates/.

I'd love to test it on more marketing emails, or content marketing -- these seem to be the two applications with the most direct ROI.
