You can monitor the status of the deliveries in your Omni instance - and view detailed information in the event of a failure - in the **Settings > Deliveries** page: ## Failed delivery notifications When a delivery fails, it will be marked as **Failed** in the **Deliveries** page. Additionally, the **creator of the delivery** will receive an email notification about the failure. ## Retrying failed deliveries Omni attempts each scheduled delivery once per occurrence and does not automatically retry a failed delivery. Omni will automatically attempt the next scheduled delivery at its normal interval. ## External destinations Scheduled deliveries and alerts in Omni depend on both Omni’s internal scheduling service and, in some cases, external systems such as connected APIs, CRMs, or email endpoints. When a delivery to an external destination fails, start by following these steps: 1. Verify that the external credentials, tokens, or permissions are valid 2. Check that the external system is reachable and not under maintenance 3. After verifying your credentials and the system's status, manually retry the delivery from the **Deliveries** page in Omni If the issue persists, contact [Omni support](#contacting-support). ## Contacting support When contacting Omni support, include the following: * The delivery ID * The timestamp of the delivery You can retrieve this information from the **Settings > Deliveries** page in Omni.
