A secure-looking inbox does not mean every route to an outside recipient had end-to-end protection.

The same email address is a convenient key for matching records across businesses and data brokers.

When every company gets the same address, it is hard to know where unwanted mail began.

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

Switch to Protonmail Reason #13: Keep your primary address away from retail mailing lists

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

Switch to Protonmail Reason #12: Give each company a different hide-my-email alias

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