Pre-Order Shipping Dates In Order Confirmation

[Maximus_Kobomo]

How could I remind customers that an item is pre-ordered in the order confirmation email?
(I am using 'Amai PreOrder Manager + Notify' for our pre-orders)

We previously had a feature set up which displayed a note next to any pre-ordered items in the order confirmation email containing a reminder that the item is pre-ordered + the expected shipping date. After resetting our emails to default, the feature no longer works and the developer who originally installed the feature is no longer available.

Does anybody know of the most effective way of including pre-order item shipping information in the Shopify email notifications?
