How to Use Domain Alias in G Suite for Gmail

G Suite powered by Google Cloud is fantastic for small to enterprise level of business looking for communication, store, collaborate and manage solution.

If you are managing your website on shared cPanel hosting, then you may not need to worry about email as it will be managed by them.

However, if hosting on Cloud or VPS, then you got to manage email by yourself. Setting up an mail server is not an easy task, and it would be a good idea to offload this to mailing solution provider like G Suite, Zoho Mail, Rackspace, Outlook, etc.

A few months back, I moved Geek Flare to Google Cloud Platform and started using G Suite to send/receive email.

G Suite cost based on some users so if you are a single owner and need just one email then your monthly cost would be $5. You can get 20% OFF by using the following coupon.


Good thing about G Suite which I learnt lately is that if you own multiple domain and need similar email on all then you can use domain alias without paying anything extra.

For ex: if you own,, and need email on all domain such as [email protected], [email protected], [email protected]

By using domain alias, you not just save the cost but also a time in logging to individual email console to read/write an email.

All your respective domain emails are available in single mail login console. If you are a single user having multiple domains, then domain alias solution sounds perfect.

I’ve three domain, and I thought I would have to spend $15 per month ($5 per domain/user) but not anymore, thanks to domain alias.

How to Add Domain Alias in G Suite?

  • Login to G Suite Admin console
  • Go to main menu >> Domains
  • Click  Add/remove domains

  • Click  “Add a Domain or A Domain Alias” on top
  • Select “Add a domain alias of $domainname.”
  • Enter a domain alias and click “Continue and Verify Domain Ownership.”

It will take few seconds, and you will be asked to verify the domain ownership by one of the following methods.

  • Add TXT record
  • HTML tag
  • HTML file upload
  • Google Analytics

Choose the one is easy for you. I prefer adding TXT record as it’s easy.

Once verified, you will get congratulation message about success. Click Continue

Go to Domains again through the main menu, and you will notice the newly added site is verified but Google is recommending to add MX records.

Click on “Set up Google MX records” and follow the on-screen instruction to add the MX record to your domain registrar.

MX Server address Priority

Note: it may take some time to get MX record propagated globally depending on domain registrar.

Well done! You’ve successfully added your additional domain to G Suites as an alias to send and receive email.

Test by sending an email to your newly added domain, and you will notice email is available to your original domain email.

How to Send Email from Alias Domain?

By default, when you add alias domain, you will receive emails on that, but if you need to send email from alias domain, then you got to do the following configuration.

Login to your original domain email

Click on Gear icon at right top and go to settings

Go to accounts tab

Click “Add another email address” under send email as

Note: when I tried above I got the following error so not sure if it’s just me. Anyway, you can fix what I did below in case you get it.

Functionality not enabled.
You must send through SMTP servers when you send as However, this functionality is not available for your account. Please contact your domain administrator for more information.

How to fix “Functionality not enabled” error?

Assuming you are still logged into G Suite Admin console

  • Go to App >>  G Suite >> Gmail >> Advanced Settings (direct link)
  • Scroll down and look for “Allow per-user outbound gateways.”

  • Tick the checkbox and save the configuration

That should do the trick. Try adding email address again, and it should work.

That’s all! Now you can send and receive an email from your alias domain.

I think this is a cool feature for people who is having multiple domains and managed by one person. This will save the cost, and all emails are handled with single login/console.

If not already, try G Suite to see how it works. Don’t forget to use the above coupon code for 20% discount.

  1. Quick question, I’ve been trying to test the alias feature but to no avail. Maybe I’m confused on how it works. So basically I’ve set it up but when I send an email to the alias it won’t land on my personal box at all. For example if my alias is [email protected] when I type an email from my personal account to [email protected] it won’t show. I do see it arrive at the admin mail account lets say [email protected] but I cannot send it to [email protected].

    On the other hand if I send an email from the alias [email protected] to a personal one it does arrive but with the address of [email protected] and not the alias one.

    Thank you in advance.

    • Without checking the entire setup, it would be difficult to pinpoint the issue. You may want to reach their support as it could be some bug and they can investigate the logs.

  2. This was great for adding another domain to my current one…and it worked.

    However I would like to add additional aliases using the new domain to the account…only the original domain is an option. Not seeing how to select the secondary domain.

  3. Hi Chandan!

    Thanks for the article. I’m “renaming” my .com to something else and a friend suggested G Suite aliasing. Which brought me here. So, for that, thank you!

    But (!!!) I want to get rid of the old domain. Or at least use it for something else, you know?

    So my question is how do I go about doing that? I mean, here’s a bigger picture:

    1. I get a domain and a G Suite going
    2. I add stuff to Google Drive
    3. I decide to change the .com name to something else
    4. I “must” keep my Google Drive assets (backups, delivered images, etc)

    Is it possible to turn the alias into the official name for the G Suite, then dissociate it from the G Suite, all the while keeping e-mails, Drive files, etc?

    Thanks in advance!

    • Hello Luiz,

      I haven’t tried changing domain and I don’t think you can make alias as a primary/official name. I can think of two options.

      1. Create a separate G Suite account with your new domain and migrate existing assets there (good if have fewer files/size).
      2. Contact G Suite to see if they can rename existing primary domain to new one.
