Brevo (formerly Sendinblue) is a cloud-based email service provider that enables organisations to manage marketing automation, transactional email, and SMS communications. The platform relays outbound mail through its own infrastructure on behalf of customer domains.
From an email infrastructure perspective, Brevo's SPF footprint is concentrated in smaller and mid-market organisations rather than among the very largest global brands. The service is geographically diverse, appearing across many top-level domains and most commonly in .com registrations. It is frequently deployed alongside Google Workspace—suggesting significant adoption among organisations using Google's productivity suite—and its growing presence in SPF records indicates it is gaining adoption as a unified platform for both transactional and marketing email.

When an organisation uses Brevo for email delivery, its domain's SPF record includes Brevo's authorised sending mechanisms. Because Brevo is a multi-tenant platform serving many unrelated senders, outbound sending reputation can be shared across the customer base. If one customer sends mail that triggers complaints, blocks, or other negative signals, it may affect the shared infrastructure reputation that other customers depend on. Organisations using Brevo should monitor their own delivery metrics independently and consider whether a dedicated or isolated sending domain is warranted if reputation separation is critical to their operations.
