Pre-launch for eBook/Guide landing page

Hey all, excited to share that I'm launching "The Guide To No Code Marketplaces" soon! In advance of launch (next Wednesday/Thursday) I went ahead and made a quick landing page for it (http://guides.everythingmarketplaces.com). I built the page using Carrd and had a few questions for the group here:

-Would love quick feedback on page if looks good from a design standpoint
-The guide is going to be free and to access, just enter email
-With the above said, I'm just using Mailchimp for email list and don't want to overwhelm people with drips following. Simple enter email, get guide, and done.
-Any examples of free (but valuable) guide or eBook launches that had successful launches in that they created some buzz on Twitter & social standpoint?

Would love to hear any other tips, tools, etc that might be helpful 🙏
