No, actually a statement like that reflects the state of email as it appears to me after 30 years of use. I have the same kind of problems I had 20 years ago. One release doesn't have "Mark As Unread" as an option in making rules. The next edition has it. The basic interface is just that, basic, and calling it simple for ease of use is just that, simple. I'm just frustrated because it seems like email is pretty important to a lot of us and it doesn't seem to be progressing as a useful app.
That's a general statement about the amount of ingenuity that had driven the development of Apple Mail, and actually all the other mail apps I've tried over the years, at least as it appears to me. The specifics are that I assume between my iMac and Macbook Pro there must be a rule conflict... not obvious, I've been over all of the rules, etc. I've tried most every suggestion I have received and I appreciate them all. But these emails disappear from the Macbook Pro, my iPhone and iMac. They're GONE! I think that just shouldn't be allowed to happen regardless of what other stupid stuff I do. I still think it's my fault in actual use but I also think something needs to cut me off at the pass when I do that. I appreciate the reply.
