Missing WooCommerce order emails
An order email can stop at four points: the order status, the notification setting, the send attempt, or delivery. Start with the status. WooCommerce's troubleshooting guide says a new order still in Pending payment does not send the email, and its email settings give each notification its own trigger, such as Processing order after payment, Completed order when the order is marked completed, and Failed order when a pending or on-hold order is marked failed. Each notification can be turned off. The transactional-emails log records a send attempt as sent, failed, disabled, or skipped. Sent means the store handed the message to its mail system. It does not mean the inbox received it. If the log says sent, delivery is a question for the host or the mail service that sends for the site, including whether the From address uses the store's domain. Prism can trace where the message stopped and repair the part the store controls.
For: An owner or authorized representative of a research-only peptide business tracing one real order whose expected email is absent.
