Hello,<p>TL;DR: You can now target your twitter ads/promoted tweets to list members/subscribers!<p>Twitter ads have a very poor targeting options, so I've built a search engine to find Twitter lists where your customers are. Try to search for example for "Wedding","Crypto", "development", "Marketing" or anything else.<p>The tool will find most of the list in this topic (I'm still improving the search engine). Once you find a list which you like you can export it as a CSV file and upload it to Twitter as a custom audience and target your ads/promoted tweets only to the member/subscribers of the list.<p>I've just used it to extract 800K twitter handles of PPC professionals!<p>Let me know your feedback. Thanks!
