I'm an inbox zero guy - I'm at my end with Apple Mail. I think I need to move to a new tool - Thunderbird? Outlook? Please hope me! I'm at my end with Apple Mail, my favorite plugin - MailTags isn't really working right. with Mavericks. Mailtags allows you to "tag' messages and then those tags can be used as 'smart' criteria for smart mailboxes.) I'm try to embody inbox zero (having nothing unread nor using my inbox as a 'holding pen') I have an iPhone where I glance at my email, but it doesn't help (beyond emergencies.) The goal is to quickly know my email at a glance. Here's the way I work right now: A email comes in, it gets checked with a bunch of rules....and put into a some smart mailbox. All spam is removed (in it's own smart mailbox for a 1x a week glance) Then all 'bacn' (that's mailing lists that I want to glance at, but NOT in my main mailbox, looked at 1-2x a day; right now it gets tagged and a smart mailbox gets built from the tag) Then colorize everyone I know (from a certain company, from my address book). A smart mailbox removes anything that is spam or bacn. So, when I glance at my 'inbox' - I can quickly tell who I know and who I don't with zero clutter.I go through email to answer right away ....or toss into an "action" folder to go through when I have real time. Mailtags is really failing me at this point (and the developer is 'not sure' when issues will be cleared up. Mail has crashed 5x today (maybe or maybe not due to the plugin.) Small notes; I have too many email accounts. That's not going to change. It's about 10, with 70% being gmail or gmail for business, an Apple iCloud account and a bunch of comcast POP3 mail (which I could get rid of or filter through another gmail account.) For example, MailPlane is out because no iCloud. Get the idea? Yes, I'd love to be able to glance at email on my iOS device, and have it integrate - but it's not my primary device; because some responses have to be long and thought out. I'm looking to hear about other tools you use for mail or how you'd solve my situation - whether it's filtering everything through a particular Gmail account, outlook, thunderbird or something else.
