Mercury SMS lets you send messages immediately or later by selecting a specific date/time. The ‘Send Later’ feature requires the Outbound Scheduler to be activated.
The Outbound Scheduler is a batch class that runs every 15 minutes to process any outbound SMS messages that have been scheduled to send at a later date/time. Click the ‘Activate’ button to enable the Outbound Scheduler.
The icon will appear indicating the Outbound Scheduler is now active.
