An alias is a secondary email address that forwards to your real inbox.
Why use them:
- Give each website a unique address
- Know who sold your data (spam reveals which alias leaked)
- Block spam by disabling one alias
- Keep your real email private
Example:
Sign up for a store with shop-amazon@youralias.com. If spam starts coming, you know Amazon leaked it — and you can disable just that alias.
Options:
- Some email providers include aliases
- Dedicated alias services let you create unlimited addresses
- Some let you reply FROM the alias too
Using aliases means one data breach doesn’t expose your main email everywhere.
