How to Fix DMARC Alignment for Brevo (Sendinblue)

Line up Brevo with DMARC: copy their DKIM + bounce-domain records from the sender auth screen into DNS.

Why Brevo trips DMARC

No auth in the Brevo dashboard means they still bounce as them — wire up DKIM + bounce domain so alignment matches your brand SPF story.

Exact DNS records

DKIM TXT + Return-Path CNAME — copy from Brevo → Senders → Domains SPF: include per Brevo documentation (verify current value)

Step-by-step fix

Step 1 Brevo → Senders & IP → Domains
Step 2 Add your domain and copy DKIM TXT + Return-Path CNAME
Step 3 Add records at your DNS host
Step 4 Ensure SPF TXT authorizes Brevo per their current include

FAQ

Is Brevo the same as Sendinblue for DNS setup?

Yes — Brevo is the rebranded Sendinblue. Use the Brevo dashboard; DNS record types are DKIM TXT and Return-Path CNAME as shown in Domains.

What are the Brevo DMARC alignment steps?

Authenticate your domain in Brevo, add DKIM and bounce CNAME records, verify SPF include, then confirm in DNS Preflight.

How do I verify Brevo domain authentication?

Brevo shows domain status when DNS is correct. Use DNS Preflight for an independent check of TXT and CNAME records.

How does SPF alignment work with Brevo?

Return-Path customization plus correct SPF TXT allows SPF to align for your sending domain.

Does Brevo support DMARC p=reject?

Yes when DKIM and SPF alignment pass — monitor aggregate reports when tightening policy.
