CPU usage always between 25-50%

While sitting idle Airmail typically uses about 30% of my CPU but often spikes higher. I don't think it is still downloading/processing messages at I've been using it for weeks. Someone from Airmail suggested disabling the Idle option in the More menu of each account but that doesn't seem to have changed anything.

I am running Version 3.5.3 (468) on 10.13.2.

    I'm also having this problem. I'm using Airmail 3.5.4 on a late 2015 MacBook Pro. The only thing that I've done is cleared the message cache recently and I think this is when this started happening. It uses so much energy I need to quit it and use Mac Mail when on battery so that it doesn't drain it too quickly.

    Me too, also on a 2017 MBP, version 3.5.5 (474). Airmail uses lots of CPU resources constantly, causing the laptop to heat up.
