Authenticate your domain with Brevo (Brevo code, DKIM record, DMARC record)

In this article, we’ll explain how to authenticate your domain. You can do this manually, automatically, or by forwarding the instructions to someone else, such as an IT team member in your organization.

Why should I authenticate my domain?

Authenticating your domain helps ensure that your emails are genuinely from you or your organization, reducing the risk of spam, phishing, and other malicious activities. This simple step helps protect your online reputation and increase trust from recipients. It is also mandatory to be compliant with Gmail and Yahoo's requirements for email senders.

➡️ To learn more, check our dedicated article What is domain authentication? (Brevo code, DKIM record, DMARC record).

Step 1. Add your domain to Brevo

To authenticate your domain, you first need to add your domain to Brevo:

  1. In Brevo, click the account dropdown and go to Senders, Domains, and Dedicated IPs > Domains.
  2. Click Add a domain. If your domain already appears on the page, click Authenticate next to it instead.

  3. Enter your domain name in the Domain name field. This is usually the part of your email address that comes after the "@" symbol and is linked to your website.
    authenticate_new_domain-name_en-us.jpeg
  4. Click Add domain.

Step 2. Authenticate your domain (Brevo code, DKIM record, DMARC record)

Depending on your domain host, you'll have two or three options available to authenticate your domain. Select the one that you want to use:

Option 1: 🤖 Authenticate the domain automatically

💡 Good to know
This option appears only for supported domain hosts.

Brevo uses Entri, our domain authentication partner, to help you add DNS records easily to your domain. When you select the option to authenticate your domain automatically, you then only need to log in to your domain host from Brevo. We will authenticate the domain for you in a few minutes.

📹 You can watch this short video to see how it works:

  1. Click Authenticate the domain automatically.
  2. Click Continue. A pop-up window appears.
  3. Click Continue. Brevo will automatically detect your domain host.
  4. Enter your domain host credentials.
  5. Click Continue. The DNS records needed to authenticate your domain will be automatically added to your domain host.
  6. (Optional) If you already have a DMARC record on your domain, you'll be asked if you want to replace it with Brevo's DMARC record. Click Okay, continue to replace it.
  7. The DNS records have been added to your domain host. From the confirmation page, click Back to domain listing.
  8. Check if your domain is authenticated:
    • If your domain is authenticated, the status next to your domain name will show as Authenticated. You're done!
      auth_domain-status_en-us.png

    • If your domain is not authenticated, the status next to your domain name will show as Not authenticated. Since full authentication can take up to 48 hours, you can try re-verifying periodically by clicking View Configuration and then Authenticate this email domain at the bottom of the page.

      💡 Good to know
      If your domain is still not authenticated after 48 hours, check our help article Troubleshooting issues with domain authentication or contact our support team for help.

Option 2: ✍️ Authenticate the domain yourself

When authenticating the domain yourself, you will have to copy and paste several values provided by Brevo (Brevo code, DKIM record, DMARC record) into your domain host account. These values are called DNS records. Then you’ll need to verify if your domain is authenticated in Brevo.

DNS_records_horiz_EN-US.png

Step 1: Add the Brevo code, DKIM record, DMARC record in your domain host account

💡 Good to know
Some steps of this process occur directly within your domain host account, separate from Brevo. Make sure you keep this page open, as you will need to refer back to it several times during this process.

Use the dropdowns below to find step-by-step instructions on adding these values to your domain host. If your domain host isn't listed, find generic instructions in the Other dropdown at the bottom ⬇️.

Amazon Route 53
❗️ Important
Amazon Route 53 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, enter the value of the extra record on a separate line below the first record.

To authenticate your domain in Amazon Route 53:

  1. Open a new tab in your web browser and log in to your Amazon Web Services account.
  2. Open the Route 53 console.
  3. In the left-side panel, select Hosted zones. This is where you'll add your DNS records.

Step 2: Verify if your domain is authenticated

You'll now verify if your domain is authenticated. Note that it may take up to 48 hours for your domain to appear as authenticated in Brevo. This delay is due to the time it can take for the DNS records you've added to propagate and be fully applied.

To verify if your domain is authenticated:

  1. In Brevo, click Authenticate this email domain at the bottom of the page displaying the DNS records. authenticate_new_verify_en-us (1) (1) (1).jpeg
  2. Check if your domain is authenticated:
    • If your domain is authenticated, you will be redirected to the Domains page, where the status next to your domain name will show as Authenticated. You're done!
      auth_domain-status_en-us.png
    • If your domain is not authenticated, a popup window will appear saying "The domain is not authenticated yet". Since it can take up to 48 hours for your domain to be fully authenticated, try re-verifying by clicking the Authenticate this email domain button periodically during that time.
      💡 Good to know
      If your domain is still not authenticated after 48 hours, check our help article Troubleshooting issues with domain authentication or contact our support team for help.

Option 3: 🤝 Ask someone else to authenticate the domain for you

💡 Good to know
The person you are sending the request to doesn't need to have a Brevo account to authenticate the domain.

If you're unfamiliar with domain authentication or don't have access to the domain host, you can ask someone, such as an IT specialist, to manually authenticate the domain for you.

  1. Enter the email address of the person you want to ask to authenticate the domain.
  2. Click Send request.
    authenticate_new_ask-someone-else_en-us.jpeg

An email has been sent to the email address you provided, explaining why it was sent and who requested their assistance. The email also includes a button to access the DNS records required to authenticate your domain.

FAQs - Domain authentication

I've authenticated my domain but it still appears as "Not authenticated" or I see a red cross ❌ under my DNS records in Brevo. What should I do?

When you authenticate your domain, it can take up to 48 hours for the changes to be fully applied. Note that Brevo has no control over this process and cannot speed it up.

If it's been less than 48 hours since you authenticated your domain:

  1. In Brevo, click the account dropdown and go to Senders, Domains, and Dedicated IPs > Domains.
  2. Click Authenticate next to the domain you authenticated.

  3. Select Authenticate the domain yourself.
  4. Click Continue.
  5. Click Authenticate this email domain at the bottom of the page.
    authenticate_new_verify_faq_en-us.png

You can repeat this process a few times in the next 48 hours. If your domain still does not appear as authenticated after 48 hours, check our troubleshooting article Troubleshooting issues with domain authentication or contact our support team for help.

Which domain should I authenticate?

You should authenticate the domain or subdomain that you use for sending emails through Brevo. This domain or subdomain is called the "sender domain". For example, if you use the email address newsletter@domain.com to send your emails, you should authenticate the domain domain.com. If you use multiple domains or subdomains to send emails, you should authenticate each of them.

My domain has already been authenticated in another Brevo account. Should I authenticate it again?

If you’ve already authenticated your domain in another Brevo account, simply complete Step 1. Add your domain to Brevo, and your domain will automatically be marked as authenticated.

It says my DMARC record is missing a rua tag. What should I do?

To comply with Gmail and Yahoo's requirements for email senders, your domain should have one DMARC record with a rua tag. If your domain already has a DMARC record but lacks a rua tag, you’ll need to update the record by adding Brevo's rua tag at the end.

  1. Open a new tab in your web browser and log in to your domain host account.
  2. Navigate to the section where you can manage the DNS records for the domain you want to authenticate.
  3. Locate and edit your existing DMARC record.
  4. In the DMARC record’s value field, add Brevo's rua tag at the end:
    ; rua=mailto:rua@dmarc.brevo.com.

  5. Save your DMARC record.

Your DMARC record should now look like this:

v=DMARC1; p=none; rua=mailto:rua@dmarc.brevo.com

Do I need to add an SPF or MX record to authenticate my domain?

The SPF and MX records are not required to authenticate a domain. We only provide these records when setting up a dedicated IP.

Can I use a 2048-bit key (sib2k) for my DKIM record of TXT type?
💡 Good to know
By default, DKIM records of CNAME type use a 2048-bit key.

By default, DKIM records of TXT type use a 1024-bit DKIM key. If you want to use a 2048-bit DKIM key to enhance your email security, contact our support team to activate it for your account. Your 2048-bit DKIM key will then appear in your DNS records with a value starting with sib2k.

1024-bit DKIM key (default) 2048-bit DKIM key
authenticate_troubleshooting_1024_en-us.png authenticate_troubleshooting_2048_en-us.png
❗️ Important

If you previously used the 1024-bit DKIM key to authenticate your domain, update your DKIM record in your domain host with the new value.

How to verify if my emails have been signed with DKIM?

Webmail services allow you to check if your email has been signed with your domain by reviewing your email headers and looking for the reference dkim=pass. If you need help finding your email headers, check our dedicated article How do I find email headers?.

email_header.jpg

In the above example from a Gmail email header, the reference dkim=pass confirms that the email is signed with the domain thegreenyoga.com.

Can I modify or delete the DNS records from my domain host once it is authenticated?

To ensure your emails are correctly sent, keep the DNS records as they are in your domain host as long as you are using Brevo to send emails. Modifying or deleting these DNS records may lead to email delivery problems or your emails being marked as spam.
