YouTubers and other social media influencers are a sort of royalty now, getting to decide by fiat which companies live or die.

But you can’t really even make the case to them anymore because like you said they can’t/won’t even read your email.

What mostly happens is they constantly provide free publicity to existing big players whose products they will cover for free and/or will do sponsored videos with.

The only real chance you have to be covered as a small player is to hope your users aggregate to the scale where they make a request often enough that it gets noticed and you get the magical blessing from above.

Not sure what my point is other than it kinda sucks. But it is what it is.
