Subject: Highest converting content upgrades

Hey {{first_name}},
I know we haven’t met (yet), but saw that you shared a post on content upgrades (from Sumome).
Thought I’d drop you a quick note about a post I’m creating on why some content upgrades convert at exponential rates and others completely flop.
The guide that I am sending next week is very comprehensive with actionable tips and tons of case study examples.
Want a heads up when it goes live?

P.S. Let me know if there’s anything I can do for you.
