2 weeks ago I've sent the first-half draft to 11 readers who've raised their hands to review.
Some have gotten back with constructive feedback (thank you 🙏)!
While others have not (probably they're busy and have forgotten 😅). I'll follow up with them after this.
Based on feedback, I've decided to put this guide in Notion instead of Google Docs / PDF.
The reasons are:
1/ I cover a lot of material (180+ pages as of this writing)
Almost complete though, the only thing left is to write the plug-n-play email series templates.

Putting the guide into a long doc makes it harder for readers to jump straight into specific topics they want to learn.
2/ I want to make this more than just a book (or ebook).
I include hands-on exercises and action-steps within each topic to encourage readers to implement what they've learned.
So the guide has to be practical and actionable.
3/ In Notion, I can create specific sections readers can jump straight to (I think it's possible - I've only been using it for 3 weeks 😅)
Even if a total beginner and wants to read from start to finish, I'll also label the guide into sequential chapters so it's easy for them.
4/ Initially before I started writing the guide, I wanted to give it away for free
But after receiving feedback from other creators, I started to have 2nd thoughts.
However, after some suggestions from Arvid Kahl, I've decided to keep it free since it's going to be a lead generator for my email marketing tool, BirdSend
