Newbie here. How do I start a chat from within eM Client?
Hi Marius, do you have a chat account or an email account such as Gmail that support the Chat feature? If you do, just add some of your contacts to the contact list, and by double clicking on their name in the chat column from sidebar, start a conversation with one of your buddies.
Hope this helps,
Paul
Hey I still couldn’t send them the message. Kindly look into my screenshot. 
Hello Salman,
these are your email contacts, not Chat.
You need to enable Chat in the right-side menu and have a Chat account setup.
