Solo ads can work for adult lead generation, but it really depends on the list you are buying from. If the list owner has a good relationship with their audience and they allow adult content, then you might see results. The problem is, many solo ad lists are built around general or business-related topics, so the leads may not respond well to adult offers. Also, email platforms can be strict about adult content, so your message might land in spam or not get delivered at all. If you find a seller who has experience with adult niches and is open about their audience type, it could be worth testing with a small budget first. You should also check if your landing page is designed in a way that doesn't get flagged too easily. What do you think about solo ads in this space?
