At 1st I thought no one was commenting, but when I logged into Blogger I could see the comments were there. But for some reason, I'm no longer getting emails notifying me of the comments.

I checked the spam folder in my email to see if I'd accidentally made the sending email address look like spam, but nothing was there.
Has anyone else noticed this?
Does anyone have any idea how to restore the emails when someone comments?
Any assistance would be appreciated!
