Schedule a send

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. Pick it under Send through in the schedule dialog; create it and add your number to it in the Twilio console first.
• A time between 15 minutes and 35 days ahead. That is Twilio’s own window. Handing over a big send takes a while too, so for large audiences the dialog asks for more lead time and says how much.

Check the time and service #

Choose the date, hour and minute in your own local time. The line below repeats when the messages go out and how far away that is; point at it to see the same time in UTC. Select the Messaging Service, then click Schedule.

While a send is scheduled #

Scheduled messages appear in History with the Scheduled status and their release time. To cancel them, pick the campaign in History’s campaign filter and click Cancel scheduled (with no campaign picked, it cancels every scheduled message). TextBay asks first, then says how many it canceled and how many had already gone out. After release they behave like any other send, delivery checks included.
