I launched the first version of Young, Not Broke with a GetRevue newsletter. I posted in a ton of UVA Facebook groups and UVA related Slack channels I was in. I had gotten a ton of support for the idea when I posted on Facebook.
The launch went well, I ended up getting about 98 people subscribed to the newsletter. However, soon after I started an internship where I wasn't allowed to publish content so I had to stop working on it :/
