Can you give me any suggestion?

Hi @akibJ. 

To add to @Kylie W comment, for pre-orders, I don’t use the notify button which only fire emails once the product is available.

Instead, I set the product to live and ensure there’s a prominent call-out in the product body copy and maybe the product title. That call-out says it’s a pre-order and when shipping is expected. Customers placed an order as normal but they will know it’s a pre-order and shipping is delayed.

I then create a pre-order flow with an ordered product trigger (for that product). The email in that flow acknowledges they’ve purchased and emphasises again that it is a pre-order, and when they can expect shipping to occur.

You’ll need to remember to switch off this flow when the product ships, or add a flow filter for the ordered product with a ‘before’ condition and the date you will start to ship if you’re confident of the date. Orders after that date won't receive the pre-order email as the product is now shipping.

Hope that helps

Andy
