Smart Trigger Push is sent when a user does (or does not do) a defined action in a defined time (for ex. "Added a product to cart" but "Not Purchased" in 2 hours). It is possible that some of these push notifications are triggered at odd hours (for ex. if user added a product at 10 pm, push message will be sent at midnight). DND feature allows you to configure idle hours during which your customers should not receive smart trigger push notifications.
You can setup Do Not Disturb (DND) time interval in the following steps:
Step 1: Head over to Push Settings or browse on MoEngage Dashboard -> Settings (sidebar) -> Push Settings
Go to FC & DND
Step 2: Here, switch ON the DND toggle button and enter the time-interval for which you wish to not send the triggered push notifications
In case you wish to deliver these push notifications after the DND period is over - switch ON the "Save & Send" toggle button. You can also mention the time interval in which multiple push notification (delayed due to DND) should be sent.
Click on "Save" and be assured that you will not send a push message to the user at odd hours.
