Messages can be scheduled to be sent at a later time or date. This can be done easily from the compose page. Just enter in the message which needs to be sent, enter in the recipient and click on the schedule message link to display a series of scheduling options.
Once you have filled in the appropriate scheduling details and are happy with when the message will be sent, just click on the send button. More information about scheduling can be found here together with details on how to cancel scheduled messages.
