Best ESP for Affiliate Marketing?

Looking to try out some different ESPs to see if I can get better deliverability than with my current set up. Does anyone have any recommendations for platforms that won't shut me down immediately due to the industry I am in? Or any tips on not getting shut down? Tried out mailchimp last week, but had my account closed immediately because "the industry I work in tends to generate a lot of complaints". Pretty sure my mistake there was that I set up a text creative and they scanned the content and decided to block. In the future will stick with mostly image to hopefully avoid that from happening again.
