How can I ensure customers receive shipping status update emails?

We mostly use ecship to handle the shipping, but some carrier not in ecship like fedex or hong kong post, when we update the tracking information, but the system didn't send the email to customers, i make sure that the box of send notification to customers had been ticked, thanks

Hi,

Did you solve this? This must be an issue with the store. You can contact Shopify support to resolve it.
