I own a small business where we offer a service in personal finance. There is only one service we provide, and can really only be done once or twice so we don't have a lot of repeat business. This ends up meaning that our list doesn't convert well for us after a while since they either signed up and we cannot service them again, or they aren't interested in our one product. Most people make that decision in the first month of signing up, and then stay in our list for the news and content.
I am trying to figure out whats the best way to monetize our list outside of our own services? We get about 15-20% opening the emails and about 5-6% click through rate.
Whats the best way to make money with this list? I think they will convert well for other services in personal finance.
