MMO Optin page traffic source

I am building my email list by creating the opt-in page to exchange the lead magnet. My target audiences are in MMO. Currently, I am running a few soloads from Udimi. I am seeking BHW experts' advice and insights to identify the best and high-quality traffic source for my opt-in page.

Thanks in advance.

Solo ads are a good start. For MMO, I'd suggest looking into active niche communities and forums where players gather. Engaging there can bring in high-quality leads.

What did you learn so far? Were solo ads winner for you?
