Wavebox (formerly WMail) is a desktop client for Gmail and Google Inbox, that lets you manage your email from a desktop app rather than your browser.The advantage of using Wavebox over your browser is that you can manage multiple Gmail and/or Google Inbox accounts from a single interface, without having to change logins or browser tabs. You also get desktop notifications whenever a new message arrives in one of your accounts.Wavebox uses the Google API to display your Inbox, so the look and feel are exactly the same. It even supports all keyboard shortcuts, file drag drop and other native integration you'd normally expect.Other features include tray icon with unread message count, spell checker and optional notification sound.The free version is limited to 2 Google accounts; you can upgrade to a paid version that adds support for Outlook and Office 365, Trello, Slack and other online content.
