Hi @Lina
You won’t be able to do this because the trigger that you want to use Aftership metric - Received Delivery only holds information about the shipping info and payment process and other shipment details like that. It doesn’t contain any info related to what product was shipped.
What we usually do for our clients in this cases is we use fulfilled order for example if the shipment is from use in the flow we add Conditional Split saying if profile property Country equals US or Canada send this email after 10 days for example, and if it is not US or Canada send email after 20 days or whatever is the usual delivery for your foreign deliveries.
Btw make sure you always add at least 5+ days from the usual delivery time. If the usual delivery is 5 days say at least 10. This way you give them chance to not receive it on time and even if they do its good them to have some time to use the product whatever it is to be able to give relevant review.
