How to Fix DMARC Alignment for Brevo (Sendinblue)

Brevo (formerly Sendinblue) DMARC alignment requires adding DKIM and Return-Path records to your DNS via the Brevo sender authentication dashboard.

Why alignment fails

Without domain authentication, Brevo cannot align DKIM and bounce SPF with your From: domain.

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

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

Step 5 Wait for authenticated status in Brevo

Step 6 Confirm alignment with DNS Preflight

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

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

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

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