mu4e is the best mail interface I've ever used because it's fast and makes it really easy to power through a huge e-mail backlog. Love the ability to capture links to emails with org-mode too.
Useful mu4e manual pages:
(use-package mu4e
:defer 20 ; Wait until 20 seconds after startup
:config
;; Load org-mode integration
(require 'org-mu4e)
;; Refresh mail using isync every 10 minutes
(setq mu4e-update-interval (* 10 60))
(setq mu4e-get-mail-command "mbsync -a")
(setq mu4e-maildir "~/Mail")
;; Use Ivy for mu4e completions (maildir folders, etc)
(setq mu4e-completing-read-function #'ivy-completing-read)
;; Make sure that moving a message (like to Trash) causes the
;; message to get a new file name. This helps to avoid the
;; dreaded "UID is N beyond highest assigned" error.
;; See this link for more info: https://stackoverflow.com/a/43461973
(setq mu4e-change-filenames-when-moving t)
;; Set up contexts for email accounts
(setq mu4e-contexts
`(,(make-mu4e-context

Use mu4e-alert to show notifications when e-mail comes in:

Provide the dw-mail package so that it can be require'd:
(provide 'dw-mail)
