I don't. Partly because it's CLI, and I don't enjoy the CLI enough to go out of my way for it, especially not with email, which(Unless you're doing some inadvisable kumar-asshole.sh stuff) is not really automatable. But largely because I rarely use mail clients at all aside from gmail on my phone. So many jobs don't have their own mail servers, and I'm not particularly interested in running a personal one either. I do, however, occasionally back up and clear out my old gmail messages. I might consider using a CLI client for that, if it was 5-minutes-or-less levels of easy to get started and write a script for. Otherwise I'd just use Thunderbird. Not that I particularly like thunderbird, I'm really not a fan of the UI, but it works.
