According to the website, the guy started on YouTube, check his YouTube page and he started videos just 9 months ago. Also according to his site, he's pretty much doing all this stuff on his own.
So, I'm inclined to think if nobody heard back yet, it's not necessarily a scam or something, seems like someone's side-gig that maybe they're trying to turn into a full-time thing and they're just a little slow getting rolling, or he's still figuring out how to do everything? The website looks pretty bare and minimal, like it was just made last week.
I'm personally not interested in print magazines at all, for anything, they just become clutter. I'd rather an e-mail newsletter myself for keeping up with the latest news about an interest, if there is any news.
Not knocking the guy or what he's trying to do, but I'm not interested in any of that "influencer" type of thing (at one point he mentioned his Instagram)—it's just not for me. Same with YouTube pipe videos.
And I'm also not against those kind of platforms or videos or "content", hell I watch YouTube all the time, but it's all educational or entertainment that's specific to my interests... I just never found "pipe content" to be either (educational or entertaining, though maybe educational if you're a new smoker). However, the stuff I do watch, most might find to be boring too.
