eM Client

eM Client is a desktop email application for Windows and macOS, with companion apps for Android and iOS. It brings email, calendar, contacts, tasks, notes and chat into one program and syncs with services such as Gmail and Hotmail, so users can manage several accounts in one place.

The software includes productivity tools like inbox categories, quick actions, message encryption, message translation and snoozing of incoming mail, along with an optional AI add-on sold with extra credits. The vendor presents it as a replacement for Microsoft Outlook or Mozilla Thunderbird and also targets companies and teams.

eM Client is a commercial product with a free version for home users and paid options for professional use, including lifetime upgrade and additional support extensions. It also now owns the Postbox email client.
