Google Domains - Authenticate your domain (DKIM)

As explained in our dedicated article Authenticate your domain to improve the deliverability of your emails (DKIM), you must add a DNS record to your web host to authenticate your domain.

In this article, we will explain how to authenticate your domain on Google Domains.

Good to know

Google Domains doesn't allow adding a record with the same type and name twice. If you have to add an extra record with the same type and name as another, add it below the first one by clicking + Add more to this record and pasting the data in the new field.

Before you start

👆Step 1: Access the Domains page

To access the Domains page:

  1. In Sendinblue, click on your name at the top-right side of the screen.
  2. Select Senders & IP.
  3. Click Domains.

⚙️ Step 2: Generate the DNS records

To generate the DNS records that you will use to authenticate your domain:

If you haven't added your domain yetIf you already added your domain
  1. Click Add a domain.
  2. Enter the domain name you wish to use to sign your emails and click Save. In our example, we are using the domain
  3. The DNS records (Sendinblue code and DKIM) that need to be added to your domain host display.

🚀 Step 3: Add the DNS records to your domain host

  1. Open a new window in your navigator and access your Google Domains account.
  2. Select the domain or subdomain that you want to configure.
  3. In the sidebar menu, select DNS.
  4. Go to the Default name servers tab.
  5. Optional: If you have used custom name servers before, click Switch to these settings.
  6. Click Manage custom records.
  7. Click Create new record.
  8. Create one DNS entry of TXT type: DKIM. 
  9. Google Domains automatically populates your domain name. When copying the Hostname field from Sendinblue, only copy the selector (circled in yellow) before your domain name and paste it into the Host name field of Google Domains: 
    Sendinblue Google Domains
  10. Copy the Value field from Sendinblue and paste it into the Data field of Google Domains.value_DKIM-SPF_EN-US.png
  11. Leave the TTL field as is and click Save
  12. Go back to Sendinblue and click Verify & Authenticate or Authenticate. 
    ❗️ Important
    It may take up to 24-48 hours for DNS changes to propagate fully.
  13. Once the configuration is complete, a green check appears next to the Value field in Sendinblue.

Your domain has been authenticated, and your emails will now be signed with your own domain name in your recipients' mailbox! 🚀⬇️
