The archive bar is a toolbar that is displayed across the archived version of your email that makes it easy to share your campaign on various social networks, see past issue or translate your campaign into other languages.
To activate (or deactivate) the archive bar:
- Go to Lists > Settings > Publicity Settings.

- Under Archive Bar, check (or uncheck) Activate the "archive bar" for this list.

Note
If you don't want the archive bar shown, you'll also need to be sure Facebook comments aren't enabled for your campaigns. You can turn these off in the Setup step of the Campaign Builder.
