Based on these posts, I signed up for MailChimp a week ago. I became my first subscriber, using another personal email address. I wanted to see what the emails looked like. I'm sure glad I did, because on my next blog post, the email notification came out, and there was my PERSONAL home address at the bottom of the email for all subscribers to see! I was horrified but super glad I subscribed to my own email list. Fortunately, I opted for Bluehost's enhanced privacy when I bought my domain so I could use their mailing address for things like this. I logged back in to MailChimp and updated my address to Bluehost's address. Problem resolved. Word of caution!
Best of luck,
