I use to regularly read your feed for years. Then they stopped coming and I didn't notice as my inbox has filled with many other sources of information. I noticed in a Working Smarter email that they featured one of your posts and attempted to re-subscribe only to be informed that email addresses at my domain (@sbcglobal.net) are banned because of spam). A most unfortunate response. The domain is not the problem. Spam is. There are filtinering tools that you can use rather than banning whole domains. Sad to have been cut from your list.
