Sending scheduled SMS messages

Message scheduling. Any date. Any time.

With SMS scheduling you can schedule all of your SMS messages - appointment reminders, promotions, greetings and notifications, in advance to ensure that messages are sent at a specific date and time. Text message scheduling is ideal for messages that need to be sent outside of working hours.
