Info products can be a good source of relatively passive income. How are you marketing your info product?
For myself, I'm writing desktop software for developers which is a market I know and something that really interests me. On top of that, there is no need for continuous uptime
I'm marketing it by writing blog posts, usually long, definitive blog posts that spell out the details of solving problems as opposed to "Top 10 Ways to Wipe Your Ass" or whatever. From there, I get people to subscribe to my email list by offering a free guide as a lead magnet. Most of the sales I've made have been via my email list.
