Seconded.  Mu4e is one of my favorite things in Emacs and makes a big
difference in my professional life.  Its search capabilities are similar
to those offered by Gmail but Mu4e is faster and I don’t need to be
online.  I wrote helm-mu to optimize the search experience even further
(gives you instant search results as you type):

As an alternative to offlineimap, I recommend mbsync (also known as
isync) which is faster and overall more mature and reliable.
