When someone texts in your Keyword, it's smart to send an auto-reply message to your Contact letting them know that they've joined your Group.
Step 1: Go To Messages > FollowUps
Head over to the FollowUps page and click the "Create a FollowUp" button.
Step 2: Create a Name & "Send Immediately"
Give your FollowUp a name and set the schedule to "Send Immediately." This setting will send the message immediately to the Contact as soon as they join your Group.
Step 3: Create Your SMS Message
Create your SMS message that you want your new Contact to receive immediately after they opt-in.
Step 4: Turn Your FollowUp "ON"
After you save your FollowUp, you can activate it (select ON), so people can receive this message.
