Pegasus Mail – a free, proprietary, standards-based electronic mail client suitable for use by single or multiple users on single computers or on local area networks.

Pegasus Mail is an e-mail client that runs on computers using Microsoft Windows: by client, we mean that it interacts directly with the user, allowing mail to be sent, read, filed, printed and otherwise manipulated through a graphical interface.

Pegasus Mail can run on single Windows computers, or local area networks – it has special support for Novell NetWare LANs that allow it to operate intuitively and with almost no maintenance. The program also supports multiple users on a single computer. Versions are available for both 32-bit Windows (Windows 98, NT4, 2000, XP and Vista) and 16-bit Windows (any version of Windows 3.1 or later). Pegasus Mail can act as a complete internal mail system on its own without needing further servers or components: it can send and receive Internet mail on its own using standard protocols (SMTP, IMAP and POP3). By adding our Mercury Mail Transport System as a mail server, you can provide fully-integrated centralized Internet e-mail services and mailing list management for your Pegasus Mail users.

The project developer is David Harris.

Nylas Mail (previously: Nylas N1) – an open-source mail client built on the modern web with Electron, React, and Flux. It was designed to be easy to extend, and many third-party plugins are available that add functionality to the client. It supports Gmail, Yahoo, Microsoft Exchange, and IMAP accounts.

The Nylas Mail user interface is styled using CSS, which means it’s easy to modify and extend. Nylas Mail comes stock with a few beautiful themes, and there are many more which have been built by community developers.

Nylas Mail was initially released and open-sourced in early 2015 and was maintained by Nylas until Spring 2017.

There are several forks of Nylas Mail that can be used instead, such as Mailspring or Nylas Mail Lives.
