In person workshop sales materials

I am going to host an in-person paid workshop at my local co-working space: The Vision for Your Extraordinary Year. I’ve given this workshop in corporate and speaking gigs, and feel confident in the content. My questions is where can I find best practices for ‘launch’ or email marketing…..I’m thinking a series of emails that would connect with a landing page. What is the best construct of the sales email; how do I price; best practices for landing pages. Thanks for any direction.
