Let agents verify every email before you send
QX checks each address through Kickbox in real time—so your outreach reaches real inboxes and your sender reputation stays clean, automatically.
Stop bouncing emails, burning sender reputation, and wasting campaigns on dead addresses. Let an agent handle it.
Every send hits a real inbox
QX verifies addresses the moment they enter your stack—catching typos, traps and dead mailboxes before a single message goes out, so your domain reputation stays pristine.
Clean lists, on autopilot
Imported a CSV, scraped a target list, or pulled contacts from your CRM? An agent runs them through Kickbox, scores each one, and quietly drops the risky ones.
Catch bad signups instantly
New form submissions and trial signups get checked in real time—fake emails, role accounts and disposable domains flagged before they pollute your database or trigger workflows.
Kickbox
Real workflows, built for your team
Build complex workflows in minutes that chain Kickbox together with the rest of your stack. Trigger them on specific events, on a schedule, or on demand.
