The **Settings** section in the SMS Campaigns module allows for advanced configuration of elements supporting your campaigns. Here, you'll find tools for personalizing and optimizing communication with recipients.

Available Tabs:

* **Links with Suffixes:** Enables the creation of shortened links used in SMS campaigns. These links help measure marketing effectiveness and save character space in message content.
* **Unsubscribe Pages:** Allows the setup of dedicated pages displayed to recipients when they click the unsubscribe link in an SMS message.
