The social media thumbnail is the preview image and text that appear when you share a link to your email campaign on social media or via messaging apps. By default, the thumbnail is comprised of the subject line and an image from your message. However, you can customize the thumbnail to use different images and text:
- Click the Social Sharing Settings button in the toolbar
- Choose Use custom content
- Input the custom title, description, and image you want to use
- Click OK
The toolbar icon is highlighted to indicate that this message is using custom settings.
