Why use aliases?
Control spam
If one of your email aliases is sold or leaked and you start to receive spam emails, you can easily turn off the compromised alias.
Stay organized
Make a new alias whenever you create an account, shop online, or sign up for a newsletter.
Protect your privacy
Aliases give you control over your identity. You never have to disclose your true email address, so you cannot be tracked and profiled by advertisers.
Prevent phishing
Aliases add an extra layer of anonymity between hackers and your inbox, helping to prevent phishing attacks, one of the biggest online security threats.
Secure your data
Hackers won’t obtain your real email address if you use an alias for an online service and it suffers a data breach. They'll only have a single-use email address that you can easily turn off.
