Switch to Protonmail Reason #14: Disable an alias after a company leaks or abuses it

A leaked address can keep drawing scams for years if it is also your permanent inbox identity.

A store needs a way to send a receipt; it does not need the address you rely on for your most important accounts.

Reusing one address everywhere lets separate companies and breach datasets join your accounts.

Invisible tracking stays normalized when readers cannot see it.

A newsletter link can carry identifiers that follow your click into a website.

The moment you open a message can become another behavioral signal for automated targeting.

Marketers can use email images to infer the type of device you use, adding detail to a customer profile.

Loading an image from a sender-controlled server can reveal your network address and approximate location.

A tiny invisible image can tell a marketer that you opened a message and when you did it.

A provider cannot casually hand over readable stored contents it does not possess in readable form.

Attachments often contain statements, IDs, and documents more revealing than the email text.

An outside sender may use ordinary email, but that does not mean the copy in your long-term mailbox should remain readable to your provider.

Private correspondence should not require every sender to become a cryptography expert.

Years of receipts, family notes, and account messages can disclose the shape of a life.

Waiting until after a profile is built leaves you fighting to remove copies from many companies.

Privacy promises matter less when nobody can inspect the software making them.

Tracking is not only a technical issue; companies also make policy choices about collecting and sharing your data.

One broken website should not force you to expose every other site to trackers.

When search, browser sync, ads, and website logins meet in one account, the resulting record becomes more revealing.

A platform should not gain a map of your reading simply because publishers embed its buttons or posts.
