I've seen the advice that you can talk to an audience and solve their problems.
How do I approach them?
Let's take "freelancers", for example.
How to approach/talk and talk to these "freelancers"?
Should I just go to r/freelancers subreddit and mass message everyone?
Should I go to twitter and search "freelancers" and cold DM everyone?
Most importantly, how should the cold message look like?
