A number of our regular visitors contact us from time to time to ask for help because they are not receiving updates from us.
There is help to be found from WordPress here.
The relevant section is set out below:
Having trouble following a blog?
Double-check that you have confirmed your subscription. If you have a WordPress.com account, you can view all of the blogs and comment threads you’re following on your Blogs I Follow page. If you don’t have an account but are following WordPress.com blogs, view your subscription settings at subscribe.wordpress.com.
Not receiving email updates?
Check your spam/junk email box. If your email client gives you the option to unblock specific email addresses, try allowing *@wordpress.com (all emails from the domain) and/or firstname.lastname@example.org addresses.
Make sure you to uncheck the box next to “Block all email updates from WordPress.com blogs you follow” on your Email Delivery Settings page.
