Issue with subscribers not receiving email notifications

A few of my blog followers recently informed me that they haven't been receiving the automated email notifications letting them know I've posted something new to my blog. The problem seems to have been going on for several weeks. I looked into what could be a cause but didn't see anything specific nor a solution in the works from Blogger or FeedBurner. Sorry for the aggravation this must be causing you. I hadn't changed my blog settings and unfortunately don't see how I can fix the issue on my end. Hopefully it will get resolved soon!
