The GroupMail Message Editor allows you include a link for your Twitter, Facebook, LinkedIn, Google+, YouTube, Instagram, Pinterest and Tumblr page.
To configure these simply click in the “Social Media Profile” button.
Enter your Profile Links in the ‘Add URLs:‘ Field above for any of the Social Media Buttons you wish to include on your GroupMail Message.
Note : It is only necessary to enter the URL for the Social Media Button your wish to Include. For example, if you only want to include a Facebook Icon, then this is the only Profile Link you need to enter.
Click on Ok to add.
You can also add these Social Media Icons to your GroupMail Signature.
Once you configure your Profile Links, GroupMail will remember these for any New Messages you create.
The Message Editor also includes a Tweet Button.
On the Message Toolbar click on this button 
to launch.
Enter your Tweet Text, your Twitter Profile URL and any Hashtags you want to include.
Then press Ok.
This inserts a Tweet Button which allow others to automatically post your tweet.
As always, if you need any help along the way, don’t hesitate to contact the GroupMail Support Team.
