Brevo is an email marketing and CRM platform — not a cold email tool. It handles marketing emails to opted-in subscribers, transactional emails (receipts, password resets), SMS campaigns, and basic CRM. People search for 'Brevo cold email' frequently, so here is the straight answer: do not use Brevo for cold outbound.

How Brevo (formerly Sendinblue) fits into a 2026 cold email stack
Cold email infrastructure in 2026 has three layers that operators need to think about independently: the sending infrastructure (the mailboxes themselves and the underlying IP reputation), the sending tool (Smartlead, Instantly, Lemlist, Saleshandy, Reply.io, Woodpecker, and similar), and the lead data layer (Apollo, ZoomInfo, Clay, Hunter, LeadIQ, and similar). Brevo (formerly Sendinblue) sits in the email marketing, transactional email, and crm layer of that stack. Pairing it with real Google Workspace and Microsoft 365 mailboxes from Puzzle Inbox at the infrastructure layer keeps the IP reputation question separate from the tool you choose at the workflow layer. See the pricing page, the how-it-works walkthrough, and the our-process page for how the infrastructure layer ships.
