mu4e and Pagkugi

An Emacs mail client built on a local Maildir index.

At a glance

A search-based workflow with fast queries, Maildir, asynchronous heavy operations, and reply and compose inside Emacs.

Where Pagkugi differs. Its primary abstraction is a global search index inside Emacs, not an independent graphical Maildir browser, and it relies on external tools to keep mail current.
