Adult email lists?

Hey guys, just wondering if anyone else in the adult niche is building an email list. I'm curious if it would even be worth doing for promoting adult offers and if the big email marketing platforms like mailchimp and klaviyo even allow adult content to be promoted.

Anyone have any knowledge on this?

Usually these users do not use their personal emails but rather fake ones or disposable ones. And they use it for multiple sign ups on different platforms. So, all emails you send is just one of the many which is usually left unread or in the spam.
