Can lost contact form messages be retrieved from Shopify admin interface?

Due to a typo in the Sender Email in out Shopify settings, it turns out that we’ve not receiving messages from the contact form on our site.

  1. Are messages accessible through the Shopify admin interface at all? If possible, we’d like to reply to any which went missing!

  2. Is there any possibility of Shopify adding an alert if emails it sends to the Sender Email bounce? The email address was pointing to a domain name with no MX record, and so were presumably bouncing, but we received no notification.
