Sender reputation: at risk

In short

How does mailfloss work with ActiveCampaign?

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