Question
I have a newsletter in the niche of meditation and spiritual music with about 2500 people - we use some affiliate links in the newsletter but they don't really bring in any revenue - how do find companies that would want to pay to be featured in our newsletter. 2500 might not be that many people but the niche is highly targeted. Also our youtube channel has just under 200,000 subscribers.
Answer
I recommend promoting the YouTube channel via the newsletter and the newsletter via the YouTube channel. With your niche being highly targeted this tactic should improve your reach. I also recommend starting a contest and offering gifts those that can generate the most sponsors. I'm sure your subscribers know of people that would sponsor your newsletter.
