I've read over and over that email is a great communication channel, and the best time to build your audience is ASAP - so I decided to start a short weekly email about topics that I am interested in. I already read articles and watch videos often, and have kept up weekly content posts in the past, so it finally clicked that I could make my first email newsletter.
I set it up with ConvertKit, and so far so good! I have my first email ready to go, it will be sent out in a few days!
