Thousands of enterprise organizations trust Kickbox to maintain clean, compliant, high-performing email lists. With fast, secure verification and a seamless Iterable integration, Kickbox makes it easy to protect your reputation, improve inbox placement, and send with confidence.

The Kickbox integration with Iterable helps you maintain a healthy, high-performing email list—whether you're cleaning an existing audience or validating new contacts in real-time.

Two Flexible Integration Options

1. List-Based Verification

Quickly connect your Iterable account to Kickbox, select a list, and start a verification job directly from your Kickbox dashboard. You'll get results that classify emails as deliverable, risky, undeliverable, or unknown. Once complete, export clean, segmented lists back into Iterable in just a few clicks—no data wrangling required.

2. Real-Time Verification via Iterable Journeys

Looking to automate list hygiene at the point of capture? Kickbox’s API integrates directly into Iterable Journeys using a custom webhook. This allows you to verify emails immediately after sign-up and automatically route contacts based on their deliverability status—before they ever receive a message.
