• Optout link: an unsubscribe link that is added automatically to each message.
• Adding tags to links: allows you to tag links for searching and audience building.
• Naming a tracked link: a "friendly name" for links that display in analytics reports.
• Link appends (using Smarty or via UI): adding a query string to links.
• Link appends by content section: add appends to links in specific sections of your message.
• Adding a contact to a list: changes list association when clicking a link.
• Updating a contact attribute: changes a contact attribute when clicking as link.
• Disable link tracking: turns off link tracking for an individual link in a message.
