I get emails from Social Bluebook, which is a company that aims to help online content creators through courses, coaching, etc. They have a free membership and a paid membership, and they also put on free webinars.
The email I got today was for a free TikTok training going on tomorrow, Friday 2/10 at 1pm EST/10am PST. If TikTok is something you want to explore a bit it might be worth checking out.
