Give users an address at another domain
You can give everyone an email address at another domain, by adding a domain alias. For example, a retailer might have domains for two different product lines and want people in the company to be able to send mail using an address from either domain.
Adding a domain alias
When you add a domain alias, everyone in your domain gets another address at the alias domain. In the example below, alias.com was added as a domain alias to the domain work.com. This gives Maria, John, and all other users an address at each domain. Mail sent to either of a user's addresses arrives in their same inbox.
How it works
- Sign up for Google services using your primary domain.
- Add a secondary domain, if you you want to share your Google Apps services with another domain.
- Add users to your Google accounts.
- Add a domain alias to your primary or secondary domains.
If you add a domain alias, everyone you add to your original domain automatically gets a second address at your alias domain. For example, firstname.lastname@example.org now has an alias address email@example.com. Mail sent to either address arrives at Maria’s same inbox. Maria can also set up her Gmail account to send mail from either address.
Note that you can’t customize the first part of a domain alias address (the part before the @ sign). In the example above, firstname.lastname@example.org can’t have the address email@example.com.
- You can add up to 20 domain aliases.
- You must own the domain name you add as a domain alias, and verify your ownership.
- Domain aliases for secondary domains must be added via the Domains API.
- You can't add a domain name that's associated with another Google account. You must first remove the domain from the other account.
- Users must still sign in to their Google accounts using their original domain address. They also use their original address to do things like sync with mobile devices and share Google Docs and Sites.
- You can add up to 30 email aliases for each user.
There are other restrictions, as well. For details, see Limitations with additional domains.
Testing Gmail against your legacy mail program? You can also add a domain alias to deliver each user's mail to both their Gmail account and their legacy mail inbox. For details, see Configure dual delivery.
