Next to Send now sits Schedule: pick a date and time, confirm, and the whole campaign is handed to Twilio immediately, marked to go out later. Twilio holds and releases the messages server-side, so your PC can be off at send time.
What scheduling needs #
- A Messaging Service. Twilio only schedules through one, whatever sender is chosen for normal sends. The schedule dialog lets you pick it; creating one takes a minute in the Twilio console and the dialog links you there.
- A time between 15 minutes and 35 days ahead. Twilio’s own window; the dialog enforces it and shows the time in your local timezone.
While a send is scheduled #
Scheduled messages appear in History with the Scheduled status and their release time. Until release you can cancel them there: select the rows and use Cancel scheduled; each cancelled message shows as such and nothing is charged for it. After release they behave like any other send, delivery tracking included.
Test mode and scheduling do not mix: with test mode on, nothing would actually be handed to Twilio, so the app asks you to switch it off first rather than pretending to schedule.
