## Why this matters

A store needs a way to send a receipt; it does not need the address you rely on for your most important accounts. Privacy is easier to defend before this information is collected than after it has spread.

## The protection

Use a forwarding alias for shopping while preserving your primary Proton address.

## Take action

Start with new purchases and change existing retail accounts gradually. A retailer still knows what you buy from it. Email protection depends on the route and settings. Ordinary mail involving outside providers is not automatically end-to-end encrypted, and email metadata is not universally hidden.
