Do you ever get an email with great information that you want to share? I do! Turning on your Social Share bar allows the recipient the opportunity to share your message with their social network(s). Many times I receive an email with great information that I would love to pass on but the Social Share bar is missing. In Constant Contact, you can turn on the Social Share bar option in the Header Box. It's not turned on by default because there are times you may not want to share easily.
Example: If I send out an announcement about an upcoming workshop it's to my benefit for it to be shareable. After each workshop, I send the slide deck to the class participants without the Social Share bar because that's a benefit for attending my class. Make it easy for your message to be shared.
