I read through emails quickly to weed out the unimportant ones (those I delete right away or send an answer back. If I reply it is no more than a couple words or sentence that is needed), if I come across an email that will take more time or thought I mark it as unread and come back to it. Once I have gone through the emails in the way I return to the ones marked unread and spend time working on those, often times I pair this with a to do list. Then work on completing the to do list based on the emails.
