What can you recommend to read about Digital marketing, especially for B2B?

I started a Course on Demand Curve and am thrilled. It helped me to polish our value proposition. Its quite expensive but you get some goodies like budget for Notion and Miro and since the value is huge, it was worth the investment from my point of view. I can also recommend to to follow Matt Learner and sign up for his Newsletter (https://twitter.com/matthlerner)
