Mail Forwarding
Revealing your real email address online can put you at risk. Email aliasing allows messages to be sent to [anything]@my-domain.com and still land in your primary inbox. This protects your real email address from being revealed. Aliases are generated automatically, the first time they are used. This approach lets you identify which provider leaked your email address, and block an alias with 1-click.
