An SMS Trigger Template allows you to save all the details necessary to trigger an SMS Sending as an SMS Trigger Template. For example, the SMS Sender name, the SMS content and text, the unsubscribe link, etc.
How that helps you:
1. Autofill Details at the Time of SMS Sending
When sending an SMS campaign, you can autofill the SMS sending details from an SMS Trigger Template rather than typing in the details manually.
2. Auto-send an SMS on successful signups
When you create a signup form to sign up customers’ mobile numbers via a single opt-in, you can configure an SMS Trigger Template to be auto-sent to customers on successful signups.
