# How to Authenticate your domain with Brevo

Authenticating your domain with **Brevo** enables Brevo to send emails on behalf of your domain securely, thereby improving your email deliverability.
This guide walks you through adding the required [DNS](https://help.ex2.com/en/article/what-is-the-domain-name-system-or-dns-oen40o/?bust=1784819338957) **records** (TXT, [CNAME](https://help.ex2.com/en/article/what-is-a-cname-record-10tdlub/?bust=1784819874395), and DMARC) in the DNS Management zone from your Client Area to complete the domain authentication process.



**Step 1: Add Your Domain in Brevo**

1. Log in to your Brevo account

2. Navigate to Senders & IPs → Domains.

3. Click Add a Domain and enter your domain name (e.g., example.com).

4. After adding the domain, select Authenticate the domain yourself to proceed.

Brevo will now display the DNS records required for authentication.


**Step 2: Copy the Required DNS Records from Brevo**

Brevo will provide you with four similar DNS records to add to your DNS Management zone:

| 3 | DKIM 2 | brevo2._domainkey | CNAME | b2.example.com.dkim.brevo.com |
| 4 | DMARC | _dmarc | TXT | v=DMARC1; p=none; rua=mailto:rua@dmarc.brevo.com |

Copy these values.

**Step 5: Verify DNS propagation**

Once the DNS records are properly configured, you would be able to verify the DNS propagation status of the domain using a [__DNS checker tool__](https://dnschecker.org/) 


**Step 6: Validate the domain in Brevo**

After the DNS records have fully propagated, return to your Brevo account to validate the domain. Once the verification is successful, Brevo will display a green checkmark beside your domain, indicating that authentication is complete.
