Common Gotchas

Brevo includes a DMARC record suggestion in its domain authentication wizard. Follow their recommendation and customize as needed.
Without domain authentication, Brevo emails use sendinblue.com in the envelope sender, causing DMARC alignment failure.
If you use Brevo for both marketing and transactional email, both types need to pass DMARC.
