Keeping track of commerce emails

WooCommerce 10.9 adds transactional email logging to help merchants monitor which emails are successfully sent and to surface explicit failure messaging for emails that fail to deliver. This new logging feature gives store owners greater visibility into their transactional email pipeline, making it easier to diagnose delivery issues with order confirmations, shipping notices, and other automated messages. The feature is part of a broader effort to improve observability in WooCommerce store operations.
