Send WordPress email through Brevo
Brevo, formerly Sendinblue, combines marketing and transactional email in one account, which suits sites that already send newsletters there. BooleanSMTP sends your site’s transactional email through the same account.
- SMTP, through Custom SMTP
How BooleanSMTP sends through Brevo
Through the Custom SMTP connection
In BooleanSMTP, add a mailer, choose Custom SMTP, and enter Brevo’s SMTP server below with your Brevo SMTP login. Logging, the fallback, retries and alerts work exactly as they do for every other connection.
| SMTP host | Port | Encryption |
|---|---|---|
| smtp-relay.brevo.com | 587 | TLS |
| smtp-relay.brevo.com | 2525 | TLS |
| smtp-relay.brevo.com | 465 | SSL |
- Username
- The SMTP login shown under Settings → SMTP & API → SMTP
- Password
- An SMTP key from the same tab; an API key does not work for SMTP
Checked against Brevo’s SMTP documentation.
Before you connect
Verify your sending domain in Brevo, then generate an SMTP key under SMTP & API. Brevo’s SMTP login is shown on the same tab, with that key as the password.
Setup guide: Custom SMTP connectionsPair it with a fallback
Pair Brevo with a second provider as the fallback so a paused account or a replaced key never stops your site’s email.
When Brevo refuses a message, BooleanSMTP tries your fallback connection at once, logs which one delivered it, and alerts you on Slack, Discord or Telegram only if every attempt fails. See the whole path
What Brevo receives
Only what sending needs: each message (recipients, subject, body, headers, attachments) and the credentials you enter for the connection, sent to Brevo when WordPress sends an email. BooleanSMTP stores those credentials encrypted in your own database. Read Brevo’s terms and privacy policy.
