SPF, DKIM and DMARC for Brevo
Short answer: Brevo mail passes Gmail, Yahoo and Microsoft checks when you turn on DKIM with your own domain
and publish a DMARC record at _dmarc (start with p=none). The exact records and clicks are below.
| SPF | — | Not needed for Brevo's domain authentication: Brevo sends with its own return-path, so your DMARC passes through DKIM. |
|---|---|---|
| DKIM | CNAME / TXT | Two CNAME records: brevo1._domainkey → b1.yourdomain-com.dkim.brevo.com and brevo2._domainkey → b2.yourdomain-com.dkim.brevo.com (the dots in your domain become dashes), plus a TXT brevo-code:… at @ that proves you own the domain. |
| DMARC | TXT at _dmarc | v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.comStart with p=none and a
mailbox you read, or a free report address that turns the reports into a dashboard; build your own. |
Step by step
- In Brevo open Senders, Domains & Dedicated IPs → Domains and add your domain.
- Let Brevo add the records for you (log in to your DNS provider from Brevo), or add them yourself.
- Manual: the
brevo-codeTXT at@, the two DKIM CNAMEs and a DMARC record at_dmarc. - Click Authenticate. You can re-check for up to 48 hours while DNS updates.
Mistakes that break it
- Cloudflare's CNAME flattening turns the DKIM CNAMEs into TXT records and DKIM fails. Switch it off for those records.
- Already have a DMARC record? Keep it. Adding
rua=mailto:rua@dmarc.brevo.comis optional and only sends reports to Brevo. - Moving from an old TXT DKIM key (Sendinblue days)? Keep it until the CNAME version shows as authenticated.
