123-reg.co.uk: Activate Gmail for Google Workspace

Tip! Only Google Workspace customers who want to use Gmail must change their MX records. You can skip this procedure and continue to use your current email provider with Google Workspace.

You’re now ready to set up Gmail as your business email for your domain (and, if you haven’t already, verify your domain).

To do this, you need to sign in to your domain host and direct the email for your domain to the Google Workspace servers. It’s like registering your new address with the post office when you move so that your mail gets delivered to the right place. We’ll walk you through the steps.

Before you begin

  • Verify that you own your domain.

    Or, you can verify now with an MX record. We’ll show you how while you're setting up the MX records.

  • Create user accounts in Google Workspace for your team.

    If your team members already use email with your domain (their email address ends with your domain), you have to create their user accounts in Google Workspace before you change any MX record settings. Otherwise, they won't be able to send or receive messages with their business address in Gmail.

Change your MX records

Step 1: Go to your DNS records at 123-reg.co.uk
  1. Open 123-reg.co.uk in a new tab.
  2. Click Control Panel at the top of the page to sign in to 123-reg.co.uk.

    If you don’t know your account information, you can reset your password or contact 123-reg support.

  3. Under Manage Active Products, locate the domain you're setting up and click Manage

    Manage button

  4. In the Advanced domain settings section, click Manage DNS.

    Manage DNS link

  5. Under Manage your DNS, click Advanced DNS.

    Advanced DNS tab

Step 2: Delete any existing MX records
  1. In the DNS table, click Trashcan Icon next to any DNS records listed with the type of MX. Don't worry, you'll add new ones in the step below.
    Note: Do not delete any other type of DNS records (A, AAAA, CNAME, TXT, SPF, or SRV).

    Delete MX records

Step 3: Add the Google MX records

To direct your email to your Google Workspace account, you have to add new MX records to your domain. These are the records that you'll need to add:

MX server address Priority
Important: Some registrars require you to add a period after the .COM in the MX server address.
  1. From the Type drop-down menu, select MX.

    MX Type drop-down option

  2. In the Hostname field, enter @.

    MX Hostname field

  3. In the Priority field, enter 1.

    MX Priority field

  4. In the Destination MX field, enter ASPMX.L.GOOGLE.COM. (including the period).

    Destination MX field

  5. Click Add.

    The DNS table will refresh and you'll see the new MX record listed.

  6. Repeat Steps 2-5, entering the remaining values (MX Server address) from the table above, and setting the Priority values respectively.

    All MX records added

    If you make a mistake after adding a record, you can edit it by clicking Edit icon.

  7. Skip this step if you already verified your domain by another method (such as TXT record, HTML file, or meta tag).

    If you need to verify your domain:

    1. In the Admin console, scroll to the Get your verification code section and click the Copy button.

      The MX records table is shown and a red circle highlights the Copy button next to the MX verification record.
    2. Paste the value in the Value/Answer/Destination/Target column.
    3. Make sure the record's priority is set to Low or to 15 or greater.
    Note: If your registrar rejects the verification code, try deleting the period at the end of .com.
Step 4: Tell Google to find your new MX records
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. Check the boxes to confirm:

    1. You've created accounts for all existing email addresses in your organization.

    2. You're ready to stop receiving messages at your old email provider and start receiving them in Google Workspace.

  3. Click Continue.

  4. Scroll to the bottom of the next page and click Activate Gmail.
