About G Suite email aliases
G Suite administrators can create email aliases for a user so they can send and receive email from another address at your domain. This article provides an overview of what email aliases are, what they’re used for, and resources for how to add them.
How it works
Every user in a G Suite account has a primary address for signing in to their account and receiving mail. If a user wants another email address, you can create an email alias for them.
You can add up to 30 email aliases for each user at no extra cost. Users must continue to sign in to their G Suite account with their primary address, not their email alias.
When to use
Email aliases are a helpful way for individuals to receive mail sent to another address all in one place. For instance, aliases are useful for sales and support staff who want a memorable, public email address. You can also use an email alias to send emails from a different address or alias.
Add an email alias
To add an email alias, you must be a G Suite administrator. Visit the G Suite Help Center to learn how to add email aliases. Use a domain alias to give everyone in your account an email alias at another domain you own.
