Email Aliases

One alias per service. When spam arrives you know exactly who sold you.

Why Aliases Work The isolation principle

ISOLATION

Each service gets a unique address. Data brokers can't link your accounts across services: they see completely different identities.

DETECTION

Spam to netflix@alias.io means Netflix sold your data. You know instantly. You cut the alias and move on.

CONTROL

Deactivate any alias instantly. The spam stops. Your real inbox is never touched. You're always in control.
