Shopping has two email moments
Should You Use Your Real Email for Online Shopping?
Completed purchases need reliable receipts, returns and support, while pre-purchase discounts and marketing can often be separated from your primary inbox.
A discount popup and a completed order look similar because both ask for email. They create very different obligations. One is marketing before a purchase; the other is a record of money already spent.
Use continuity for completed orders
Receipts, shipping updates, refunds, warranties and disputes can matter after delivery. A durable address gives you a reliable record trail.
A dedicated shopping inbox can be a good compromise
If you buy online often, a secondary durable address keeps promotions and order mail away from your primary inbox while preserving future access.
Pre-purchase marketing can be treated separately
A coupon form you may never use does not create the same recovery need as an order. A temporary address can make sense for a truly one-off promotion when no later access matters.
Do not sacrifice account security for inbox cleanliness
For stores that save payment methods, loyalty value or purchase history, use strong account security and an address you can recover later.
For actual purchases, favor durable access. Separate the marketing problem from the order-record problem.

Create a private temporary inbox when you need to receive mail without automatically giving a low-stakes site your primary address.
