Details
Here's where you can manage some of the details of your SMS

You may edit the sender name under Sender name.

If you added a link to your SMS, recipients may interact with them, and their interactions will be tracked and stored in APSIS One Profiles. If you untick the Track links box, Profiles who click the link in their mobile phone and other corresponding information will not be a part of the SMS Report.

Unsubscribe Settings
For all kinds of communications, your subscribers will have the option to opt-out or unsubscribe.
This will happen when they click your unsubscribe link in your SMS. This link will lead them to a landing page where they can confirm their wish to unsubscribe; depending on your options, you will either display a confirmation message or lead them to a page of your choice.

Make sure that your ##Unsubscribe## Data Tag is added into the message.

Did you test your unsubscribe link?
It's important to always include an unsubscribe link in your SMS messages. When testing an SMS, you can test the unsubscribe link to make sure that it takes you to the unsubscribe landing page and that your settings are correct.
Feel free to click the unsubscribe link in the SMS, and then the button in the landing page. And don't worry, since it's only a test SMS, no actions will be recorded and nobody will be unsubscribed based on the link in the test SMS.

Ready?
If your SMS looks good, go ahead and click Next step in the Bottom bar to proceed.
