My cold emails are not getting opened. I'm a video editor looking for clients so I created a free PDF as a lead generator.

Most of my cold emails are going to spam (I think). I have sent various variations of this email and in bulk too, I think I made some mistakes as a rookie and now my emails are going to spam so I stopped since a few days now and today I began doing courses on email marketing, yours was my first course since I paused email marketing until I learn to do it better. Anyway, please provide feedback on my email. I'm targeting YouTubers.
