Mailgun documentation states that `events` API has been deprecated in favour of `Logs` api - Events: https://documentation.mailgun.com/docs/mailgun/api-reference/openapi-final/tag/Events/#tag/Events/operation/get-v3-domain_name-events - Logs: https://documentation.mailgun.com/docs/mailgun/api-reference/openapi-final/tag/Logs/ It may be possible we would need to update mailgun sdk and the api used for message status confirmation
