Step-by-step walkthrough
The recording predates the Message Service ID field. Fill that in too — the steps are otherwise

Before you send at volume
Twilio requires 10DLC registration for application-to-person SMS to US numbers. Unregistered traffic gets filtered by the carriers, not by Twilio — so messages simply stop arriving with no obvious error. Register your brand and campaign in the Twilio Console before you turn on follow-up sequences, and keep an eye on Messaging health afterwards.Troubleshooting
