Message Scheduling is now generally available through Twilio's Programmable Messaging API, allowing users to schedule SMS, MMS, or WhatsApp messages to be delivered at a future date and time. The feature has been enhanced to be HIPAA eligible and can schedule messages as soon as 15 minutes out, rather than the previous 60-minute criteria. This allows businesses to automate and simplify timed delivery of their messages, such as appointment reminders, notifications, and promotional messaging, without needing to implement own queuing or scheduling logic. To use Message Scheduling, users need to have their SMS-capable numbers configured inside a Messaging Service and reference the service in their API request when using the feature.
