mailflossConvertKit Email Verification
Improve deliverability, reduce bounces, and clean creator email lists with seamless ConvertKit email verification from mailfloss.
How does mailfloss work with ConvertKit?
mailfloss connects directly to ConvertKit 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 ConvertKit 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.
