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:- Verify that the external credentials, tokens, or permissions are valid
- Check that the external system is reachable and not under maintenance
- After verifying your credentials and the system’s status, manually retry the delivery from the Deliveries page in Omni
Email domain restrictions
If an email delivery fails or is blocked, the recipient’s email domain may not be included in your organization’s domain allowlist. When a domain allowlist is configured, Omni only sends deliveries to recipients whose email addresses match one of the allowed domains. To resolve this issue:- Check if domain restrictions are in place by navigating to Settings > Deliveries > Email tab > Domain allowlist
- Either add the recipient’s domain to the allowlist (up to 10 domains can be configured), or click Clear allowlist to remove all domain restrictions
SFTP address errors
If a delivery to an SFTP server fails with an Invalid SFTP address error, verify the following:- The address starts with
sftp://— for example,sftp://ftp.example.com/incoming/ - The port is entered in the Port field, not embedded in the address (for example,
sftp://host:8022/pathis invalid) - The username is entered in the Username field, not embedded in the address (for example,
sftp://user@host/pathis invalid)
Contacting support
