Switch to Protonmail Reason #20: Limit the damage when a newsletter sells or shares your address

Why this matters

A newsletter signup can spread beyond the publisher through partners, brokers, or a breach. Privacy is easier to defend before this information is collected than after it has spread.

The protection

A dedicated alias contains the fallout to one address you can disable.

Take action

Give newsletters aliases, not your core address. Unsubscribe first when appropriate, then disable an abused alias. 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.
