Franz is freeware messaging and email client with 23 services. This help you more easily to do it all in one freeware.
Franz available on Mac, Windows (32 & 64 bit), and Linux (32 & 64 bit). At first I know of a friend Franz Mac users, which at that time did not support Windows. So I signed up to receive updates. A few months later launched the Windows version, and without a long wait for the download and installation.
I use various chat services, such as WhatsApp, Messenger, Telegram, Skype, and Hangout, which is useful to supporting my work. Yes, I am a person who works in the office and field and require lot of communication with the teams using variety of chat services. With Franz, only needed to run one application, and let it live through the day.
A few days ago there is updates that add the email feature. Some email services are supported, such as Inbox by GMail, GMail, and Outlook.com. It makes me more happy using it.
