How to Verify Domains in Brevo Easily 2026

Domain verification isn't under Campaigns or Contacts. It's filed under Settings, in the Organization settings block alongside Users, SMTP & API, and Security.

Brevo's settings sidebar groups it as "Senders, domains, IPs," easy to scroll past if you're expecting it under a marketing-labeled menu. Click into that section to reach the Domains tab, where you add and manage your sending domains.

In the Domains tab, click Add a domain and enter your root domain, just the domain itself, like yourcompany.com, with no https:// prefix and no trailing path. Save it to move into the verification options.

Brevo offers two routes. Automatic authentication signs into your domain registrar directly and lets Brevo add the required DNS entries for you, faster if your registrar is one of the supported partners. The manual route generates the record values so you can add them yourself through your host's DNS zone editor, useful if your registrar isn't supported for automatic setup, or if DNS is managed by someone else on your team.

Two records matter here: a Brevo code that proves ownership, and a DKIM record that lets receiving mail servers confirm your messages weren't altered in transit. The Brevo code is always a single TXT record.

DKIM is where accounts differ: Brevo's current default sets up two CNAME records, typically named mail._domainkey and mail2._domainkey, that point at Brevo's own signing infrastructure and rotate their keys automatically without you touching DNS again. Some accounts instead show a single TXT record for DKIM, an older format using a fixed key (1024-bit by default, with 2048-bit available on request) that doesn't rotate on its own.

Which one you see depends on how the domain was set up; the important part is matching the record type Brevo displays exactly. Entering a CNAME's target value into a TXT record, or the reverse, is the most common way this step goes wrong.

If you went the manual route, log into whatever service manages your DNS, your registrar or a separate host, and open the zone editor. Create each record using the exact type, host name, and value Brevo displayed, TXT or CNAME as shown, not assumed. Copy the values instead of retyping them; a single missing character is enough to fail verification.

DNS changes don't apply instantly. Propagation can take anywhere from a few minutes to around 48 hours, depending on your host and existing record TTLs. Return to the Domains tab periodically and use Brevo's check configuration option to refresh the status; once every record resolves correctly, the domain becomes available to select as a sender for your campaigns.
