Back in the pre-smartphone days I used to set up folders in my email client and have rules for them. Basically dumped all the notification emails that I don't need to read but might want to refer to later in folders.... stuff like UPS tracking numbers, order confirmations, bill paid notifications, etc, etc. These days 98% of the time when I check my email it's on my iphone which doesn't support folders/rules. As far as I can tell, gmail doesn't let you do this either... they have some category/labels thing but it doesn't seem to let me manually create folders and sorting rules and it doesn't do much good on my phone. Anyone know an app or some hidden button to hit in gmail to get it to do what I want? I can't believe we've come so far and lost this basic email feature. I'm sick of manually deleting dozens of useless emails every day or having a cluttered inbox all the time.
