Receiving multiple of the same notificaiton

I am a new user, and have subscribed to my blog post notification emails on my blog through a second email address so that I can monitor how they come across. Today was my first day receiving the notifications (new blog, and I am currently the only subscriber due to newness.) However, I received the same blog post notification email 17 times so far today. I am subscribed one time, and it is accurately listed in my dashboard that I have one active contact (myself.) Do I have something in my settings that would be incorrectly configured to cause this? I do not want other subscribers to have to deal with constant emails like I have all day today. I am currently annoying myself and not sure how to stop it.
