None of my followers have been receiving new post notifications from my blog recently. Those emails (which used to go out without a problem) are not in spam folders now, they simply don't go out, according to everyone I've asked. So I "test-subscribed" myself via an old email address, and sure enough, nothing arrived following a recent new post. How can I fix this? Thanks.
The blog I need help with is memoryidentity.wordpress.com.
