mailflossBrevo email verification, on autopilot.
Connect mailfloss to Brevo and we'll quietly catch the typos, bounces, and dead addresses dragging down your sender reputation across every leads and contacts segment you send to.
How does mailfloss work with Brevo?
mailfloss connects directly to Brevo and automatically verifies your contacts — catching hard bounces, fixing typos like gmial.com, and removing disposable or risky addresses before they hurt your sender reputation. It runs in the background on a schedule and can check new signups in real time, so your Brevo list stays deliverable without manual exports or CSV round-trips. Most teams start with Typo Fixer plus daily cleanup.
Three clicks. Then it just runs.
