Alternatively, have you stopped opening my letters? The way my email provider works, subscribers have to stay active and engaged to continue getting updates. If too much time passes without you opening a message from me, my provider assumes you’re no longer interested and will move you to the “inactive” list. The inactive list doesn’t get sent anything without an override to the system, which I won’t always do. So, the best way to continue receiving updates is to open your messages, even if you don’t actually read them.
