Regal Send failed email alerts
Updated September 20, 2026
Regal Send failed email alerts#
Regal Send failed email alerts notify the WordPress administrator when a mailer cannot accept an email. They are useful when a provider credential, SMTP connection or sender setting needs attention.
Choose how alerts are delivered#
- In WordPress, open Regal Send > Settings.
- Enable Show failed-email alerts in WordPress to display the actionable administrator notice.
- Enable Email administrators about failed delivery to receive an email alert.
- Add any additional recipients, separated by commas, spaces or new lines, then save.
The WordPress Administration Email Address is always included. Additional recipients receive the same alert.
How delivery failure alerts work#
Regal Send uses PHP mail directly for the alert instead of the selected Regal Send mailer. This prevents a failed provider, such as an invalid API key or unavailable SMTP host, from causing an email alert loop.
If automatic delivery retries are enabled, Regal Send sends an alert only after all configured attempts have failed. A successful retry is recorded as sent and does not create a failure alert.
Matching failures are rate-limited to one alert every 15 minutes. A different failure reason can send a new alert immediately. The email includes the site name, latest failure time, affected mailer, safe error message and a link to failed email logs. It never includes saved credentials or the original email content.
If an alert does not arrive#
- Check that the WordPress Administration Email Address is valid.
- Check the extra recipient addresses for spelling errors.
- Review the failed logs from the link in the WordPress notice.
- Confirm that the server can send PHP mail. The fallback cannot use the failed provider by design.
- Use Regal Send > Test Email after correcting the provider configuration.
