    I've given Apple Mail, Airmail 2 and Thunderbird (a few years back) and seemed to not have any luck with CPU usage and therefore reduced battery life. Mail just stays at 100% CPU for no reason. Airmail bounces up and down from 20% to 80% but never lets go.

    Anyone have experience with mail clients that don't suck up resources? Would switch immediately!

    Powermail uses 0.4% CPU and 26.4MB when idle. It is extremely easy to back up your mail and settings too, a simple finder copy of one folder in the user's mail folder does that. I have used it with no problems on El Cap, and Yosemite.

    Have you investigated the issue fully because mail in OS X is fairly light weight

    If you see Mail going 100% CPU utilization all the time then you might have a serious issue with your Mac to begin with. This should only be the case during brief periods when messages are synchronized. Most of the time, Mail COU utilization is exactly 0

    Interesting, so Apple Mail doesn't consume resources constantly?

    Let me give that another try then. I do have over 8 years of mail in Gmail so not sure if it just takes a few days to calm down.
