When you’re trying to build a mailing list, it can be demoralizing when someone leaves. It’s a clear signal that your messaging did not hit the spot with at least one person.
But keep in mind you’re not working for the masses. You’re working for your core audience. And those are the people who want to hear from you so much they’ll look forward to your emails and miss them if they don’t come.
People who unsubscribe are doing you a favor. They’re clearing the way and making it possible for you concentrate on only your core group of super fans.
