Hey, anybody can recommend proven Solo Ads/Dedicated Email providers with big lists suitable for any major verticals (news, finance, health, biz opp, survival)?
For those who don't know what Solo Ads are: The provider usually has access to email lists that are sorted by niche or demographic, I pick email lists that I am most interested in and have an offer for, provide an email with content + aff/funnel link, pay money for amount of sent emails, provider sends emails to the lists
Mainly interested in the US, but any other Geos would be awesome too for scaling.
