&#x20;If a campaign cannot be displayed (e.g., due to technical issues), subscribers will receive a default notification saying, "Your site has been updated in the background." This behavior is determined by browser settings.

To provide your subscribers with a more informative message, you can customize the “Default notification” title and content. For example, you could set a message like, "Check out our latest offers and promotions." This customized notification will automatically be displayed if technical difficulties prevent original campaign from being delivered.
