What’s G Suite (or, as it used to be known, Google Apps)… primary domain, secondary domain and alias domain? This is a question that many buyers, businesses, particularly startups, have trouble answering. In this post, I’m going to try to help you understand G Suite (formally Google Apps) domain name basics
What’s primary domain?
When you sign up for a G Suite (formally Google Apps) account, you provide an Internet domain name that becomes the primary domain associated with your G Suite account. You and your users get account names and email addresses at this domain and you can host your website, built in Google Sites if you like, at this domain. When you sign up a Google Apps legacy account at http://googleappslegacy.com, we will change the primary domain to your domain.
What’s a domain alias?
As the term “Alias” suggests, domain aliases are the domain name which will not be used to create new separate emails ids, rather it will link to the email ids you already have with your primary domain. You can add a domain to your account as a domain alias to give everyone in your domain another email address at the domain alias. Mail sent to either of a user’s addresses arrives at the user’s same Gmail inbox.
As an example, lets say in your G Suite account you have a primary domain named example.com, but as you have a multinational business, you have country specific domains too, like example.co.in, example.fr, example.tk etc. Now if you create 3 separate email ids for each of your employees, say [email protected] example.com, [email protected] example.co & [email protected] example.us. That person (Jhon) has to maintain all three email accounts daily and it would become a nightmare.
Now if you add example.com as primary domain of your Google Apps account but example.co.in, example.tk as domain aliases, then even if someone sends an email to [email protected] example.us it will still go to [email protected] example.com and the person has to maintain only one email id.
What’s a secondary domain?
In addition to your primary domain, you can add additional domains to your account to let users in those domains use your services, too. When you add a domain that has its own users, we refer to it as a secondary domain. Unlike Domain Aliases, the secondary domain will allow you to create separate email ids with a separate domain name.
So, if you have example.us and example.eu added as secondary domain in your account, you will be able to create two separate email ids, i.e. [email protected] and [email protected] – which is something you won’t be able to do with Domain Alias.
