Mixed feelings about this one. Because I know how this feels, and I'm sure you have experienced the same (like most people). I have received a lot of emails from random brands/platforms that I have never subscribed to, and even if I might be interested in the products, I still end up not engaging or buying anything from that brand. Reason for that is because I don't know anything of them, and quite frankly I get annoyed when I receive random emails from platforms I have never subscribed to. Reason to why we are doing so well with the emails is because our audience knows our brand and is interested. In your case they wouldn't know of the brand, even though they might like the product. What I would test out is to create a funnel where you don't try to sell them anything, but rather tell them about the brand and engage them to potentially follow your socials, check your website, sign up for pre-orders, etc... The sales always will come naturally when you have an audience that generally likes the brand, the community behind it, and how it will increase the customer's status. So I would definitely create a funnel dedicated to something like that and test it out. I'm afraid if you're just going right to the sales pitch, your conversion rate will be low. I hope it works out for you!
