How do I know the customer received the shipping confirmation email?

Hope someone can shed some light onto this. This might sound really cringy and nooby.

Please note: I use AutoDS automatic fulfillment.

I recently got an order and can see that the order confirmation email was sent to the customer.

When the customer placed an order, I saw on the timeline that an email was sent for the order confirmation.

Now that the product has shipped, I don’t see a preview of the email that should be sent to the customer for the shipping confirmation.

I’m just worried that the customer did not receive the shipping confirmation email.

How do I know if the shipping confirmation was emailed to the customer?
And if it didn’t, is this something that needs to be handled within Shopify or AutoDS?

Thank you for anyone that can answer this question!

If the order timeline says “Order confirmation email was sent to” it means the order confirmation you have configured in Shopify was sent to them.

If the timeline does not show that, it was not sent.

Since you have an app controlling fulfillment, I would contact them. The fulfilling app has the option to trigger the customer email notification or not.
