I have a newsletter sign-up on all my books and my website, but honestly I haven't put out that many newsletters.
One of the main reasons is time. And since I blog here each week, I figure that's enough as I value everyone's time--I also value mine. I subscribe to authors and other content creators whom I receive multiple e-mail newsletters in a single day. Some I look forward to getting, like Seth Godin and Simon Sinek, but others . . . not so much. I haven't unsubscribed to any of these.
I'm still collecting e-mail addresses from those who subscribe to the newsletter. That's not going away. And I will send newsletters.
So why do I keep up with this blog? Because it's easy for me to communicate my thoughts on here, it doesn't take much time, and I love sharing weekly updates on what I'm working on. Here's a link to my very first blog post--not much has changed in my approach.
