Five myths about reducing email correlation

The five myths

• It makes you anonymous
• It stops every phishing message
• It removes the need for strong authentication
• Every address should be temporary
• More addresses always mean more confusion

What is actually true

Use distinct aliases where cross-context matching would reveal too much. That can reduce correlation, improve context and make one exposed relationship easier to replace. It is a control surface, not an invisibility cloak.

Why the distinction matters

A shopping profile and public forum account share nothing obvious except one email field. The address can tell you which relationship is involved, but it cannot certify the sender or erase information shared elsewhere.

Good tools solve a named problem. Myths ask them to solve every problem.

Use the modest superpower

Payments, phones, devices and addresses can still connect records.

• Separate revealing contexts
• Avoid predictable aliases
• Reduce repeated identifiers
• Review public exposure
