You can easily share your SmartFrames via email. Just hover over the Share button on your SmartFrame and find the letter icon.
This email includes a small (400px-wide) JPEG thumbnail of the SmartFrame shared, which links either to the page where the SmartFrame is embedded (default) or a standalone Image Page. You can change this in the Control section of the Admin Panel.
If you wish, you can also include a personalized message in this email.
