How to set up DMARC for Brevo (ex Sendinblue) in Valimail

Updated over a week ago
SPF(supported) (dedicated IP)
DKIM(recommended) (dedicated subdomain)

This article covers the SPF and DKIM authentication processes for Brevo (ex Sendinblue) and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

With a dedicated IP, you will configure a dedicated subdomain for Brevo. This can either be hosted on your DNS or the subdomain can be delegated to Brevo.

Configuring DKIM authentication for your Brevo emails

Step 1: Access the Domains page

To access the Domains page:

1. In Brevo, 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:

1. Click Add a domain.

3. The Brevo code and SPF will need to be added to your domain host. The DKIM key needs to be added in Valimail.

4. After you publish the records needed in the DNS and Valimail, click Verify & Authenticate or Authenticate.

5. Once the configuration is complete, a green check appears next to the Value fields for DKIM and SPF records.

IMPORTANT: Brevo has a verification process that checks to see if a customer has correctly published SPF and DKIM records before they will send in an aligned way. This check is only done when Brevo is being onboarded to a domain that is already pointing SPF to Valimail and not when Brevo was already configured as a sender in the customer's DNS before pointing SPF to Valimail. Brevo does a simple text match for their SPF include and is not able to recognize the Valimail Macros. In order to bypass this, the SPF include for Brevo needs to be temporarily added after the Valimail Macro, the record now showing like this:

v=spf1 include:%{i}._ip.%{h}._ehlo.%{d}._spf.vali.email include spf.sendinblue.com ~all

The Brevo include can safely be removed once we make sure that the emails are being DKIM signed and that they have verified their include exists.
