Dedicated Tracking Email Is Not Sent
Check the billing email
The dedicated tracking email requires a billing email on the WooCommerce order.
Manual order workflow
When adding the tracking entry, make sure Send tracking email to customer is enabled before saving the order.
CSV workflow
Before importing, enable Send tracking email for newly imported tracking entries.
WooCommerce mail delivery
Because Deviking uses the WooCommerce mailer, also verify the site’s general WordPress/WooCommerce email delivery if no messages are reaching customers.
