Shopify is treating the same customer with different address as 2 different customer -New Subscriber

Hi,

We are giving Free shipping to new subscribers.

In order to calculate shipping charge we use an app called Ship Easy (ShipX).

It has a logic - if customer.previous order = 0 then shipping charge = 0.

I can see customers use different delivery address to get Free Delivery.

Why does Shopify treat the same customer (same email id and phone number) with different delivery addresses as two different customers? How can we stop this?

If the person with the same email id and phone already received free delivery then we do not want to give them free delivery again.

Thanks,

In Shopify the customer email address is what makes them a unique customer. You can't add a 2nd customer with the same email address (if you want to test go to Customers > Add and then try to create a customer with same email as an existing customer).

If you're seeing different behavior, it's likely something different than the Shopify Customer. For example if you're talking about free shipping, that happens before checkout, so it's something with either your theme code or the app if you're using that. I would contact the app and ask them for advice.

Hello @paulson1 ,

I think it is not Shopify issue, it is the bug on the app that you are using. You can try to contact them to fix it.
