Can I choose which Keap lists or segments are cleaned?

Yes. Choose which Keap connections and lists mailfloss watches, then set cleanup rules for each connection. That lets you review one Keap workflow while automating another instead of forcing every connection to use the same cleanup behavior.

What happens to invalid addresses in Keap?

You choose the workflow. mailfloss can keep an address for review, clean it automatically, update fields, or notify another tool according to the rules set for that Keap connection. Start with review when you want oversight, then automate the actions you are comfortable applying.

Will mailfloss show up inside Keap?

mailfloss runs from the mailfloss dashboard and manages Keap contacts in the background. You control the cleanup settings in mailfloss; scheduled checks can then write fixes and removals back to Keap according to the rules you selected.

In short

How does mailfloss work with Keap?

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