@noctuaminervae I've been using gnus for a while but did not really get in the flow (my experiment with mu4e was even shorter). At that time I started using conkeror browser which was pretty ok with the old gmail web client. Now I'm on thunderbird, mostly because of gmail again, but I did not find a good alternative to thunderbird yet.
If we'll have #emacs meetup I'll be very interested your email client config.
