Show the location customers signed up in the requests

I’m now manually emailing customers when a item comes back into stock due to the app not being able to work with different stock locations.

The one problem with that is that I don’t know where the customer is located, I only know their email address. Is there any way you can inform me which country the customer is located in?

That way I will be able to correctly inform the customer depending on whether the item is back in stock in their country.
