I've been working in the Shopify Ecosystem for over 3 years now from the merchant, partner and app developer roles. While recently working on my wife's Shopify site (www.mom-aid.com), I realized that it was hard to discover new Shopify apps through the marketplace.
I hypothesized that it would be easier if there was a way to get a digest of all the new apps published. I figured I could send out a curated weekly newsletter with all of the apps published from the previous week.
To test the idea, I launched a landing page and spread it around to various channels to see if anyone would sign up.
The channels I tested were my personal network, Shopify Forums, and Reddit.
