How does mailfloss work with Sendinblue?

mailfloss connects directly to Sendinblue 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 Sendinblue list stays deliverable without manual exports or CSV round-trips. Most teams start with Typo Fixer plus daily cleanup.
