Its functions include sending and receiving email, managing calendars, tasks, contacts,[1] notes, and chat (both XMPP-based and multichat such as Slack and MS Teams).[2] It was originally released in 2007 and still receives regular updates as of May 2024.[3] Versions for Android and iOS were released in 2024.[4]
Features
eM Client has a range of features for handling email, including advanced rules management, mass mail, delayed send, or a built-in translator for incoming and outgoing messages. It supports signatures, Quick Text, and tagging and categorization for easy searching.[5] Watch for Replies and Snooze Email functions are available, as well as direct cloud attachments from cloud services like Dropbox, Google Drive, OneDrive, ownCloud or Nextcloud.[6]
eM Client provides also a lookup service for GnuPG public keys (eM Keybook) in order to more easily send encrypted communication via email, and generally simplify PGP encryption in email communication.[6]
eM Client allows extensive appearance customization.[11]
eM Client 10, released in 2024,[12] also provides AI features for composing messages and replies, Inbox categories and Quick Actions which allow users to create their own macros.
