This article applies to users who created a Brevo account before June 29, 2023. If you created your account after this date, check our dedicated article to learn about the new domain authentication process.

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

If you're unfamiliar with domain authentication, check out our dedicated article About domain authentication (DKIM).
Verify your domain using DNS records, a hosted file, or an email verification code. You can verify and authenticate your domain simultaneously with DNS records. To learn more, check our dedicated article Verify your domain to approve new senders automatically.
The DKIM key generated when adding your domain is a standard 1024-bit DKIM key. If you want to use a 2048-bit DKIM key to enhance your email security, ask our support team to activate it for your account. Your 2048-bit DKIM key will appear in your generated DNS records for email authentication with a Hostname starting with sib2k:

👆Step 1: Access the Domains page

To access the Domains page:

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

⚙️ Step 2: Generate the DNS records

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

Click Add a domain.
Enter the domain name you wish to use to sign your emails and click Save. In our example, we are using the domain domain.com.
The DNS records (Brevo code and DKIM) that need to be added to your domain host display.

Under the domain name that you want to use, you will either need to click:

Authenticate, if you already verified your domain, or
Verify, if you haven't verified your domain yet.

The DNS record (DKIM) that needs to be added to your domain host display.

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

Open a new window in your navigator and access your Google Domains account.
Select the domain or subdomain that you want to configure.
In the sidebar menu, select DNS.
Go to the Default name servers tab.
Optional: If you have used custom name servers before, click Switch to these settings.
Click Manage custom records.
Click Create new record.
Create one DNS entry of TXT type: DKIM.
Google Domains automatically populates your domain name. When copying the Hostname field from Brevo, only copy the selector (circled in yellow) before your domain name and paste it into the Host name field of Google Domains:

Brevo Google Domains
Copy the Value field from Brevo and paste it into the Data field of Google Domains.
Leave the TTL field as is and click Save.
Go back to Brevo and click Verify & Authenticate or Authenticate.

❗️ Important
It may take up to 24-48 hours for DNS changes to propagate fully.
Once the configuration is complete, a green check appears next to the Value field in Brevo.

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