If you notice your Automated Message Campaign isn't sending or scheduling your messages, check the settings in the campaign. You might be missing this step!
Step 1: Go into your AMC edit screen (click the pencil icon next to your campaign).
Step 2: Check the recipient for each message. is "none selected" showing?
Step 3: If "none selected" is showing, click the drop down and select who you want your message sent to. "subscriber" means the person who texted or was added to the campaign. Internal allows you to choose a user to send an internal message to.
Once you update those messages (you need to check every message) and click save, people added to the campaign from this point on will receive your AMC messages.
*Anyone currently in the campaign will not receive updates made after the time they were added to that campaign. So changes made to a campaign do not update for everyone.
