I use Gmail. It is, by far, the best email service. You literally can't pay (any affordable amount) for better email service.
I would guess that most, maybe 75 - 85%, of my email is worthless. These emails are not spam or junk, they are from real people here at UWM. However, many of these emails are not for me. I am on these lists that send general FYI-type of emails, but there is always the possibility that I need or want to know about something contained in these emails.
The real problem is that these emails get in my way of reading the more important emails that show up less often. My previous solution was to create a special label, which I called "Normal", and set up filters to send these normal emails there, skipping my inbox. This worked pretty well, but it requires effort on my part to set up the filters.
Yesterday, I started using the new beta version of Priority Inbox in Gmail. I have high expectations for its effectiveness, so I hope that I will not be disappointed. I will post again in the future to let you know how well it works.
