How to Set Up Transactional Email Automation in Brevo in 2026 – Full Guide
Transactional email automation is one of the most important communication systems for modern businesses. Unlike marketing emails that promote products or services, transactional emails are triggered by specific user actions and provide important information such as account confirmations, password resets, order updates, invoices, notifications, and onboarding messages.
