Kickbox
Fast, Reliable, & Accurate Email Verification
Kickbox is an email verification platform that checks whether addresses are deliverable, risky, or undelundeliverable, helping organizations maintain clean data, reduce bounces, and protect sender reputation. It combines bulk list cleaning, real-time verification at the point of capture, and deliverability consulting.
Core products include Email List Verification for bulk cleanup, an Email Verification API for webforms, signups, mobile apps, and POS, and an Email Threat Score that assigns a 0–5 risk rating to flag addresses tied to abuse or poor sending reputation. Deliverability Consulting offers audits and ongoing guidance. Native integrations cover tools such as Mailchimp, HubSpot, Salesforce, Klaviyo, Braze, Iterable, and Marketo, with additional connections available through Zapier and third-party options, plus automation for scheduled cleaning and form verification.
Kickbox is aimed at developers, agencies, enterprises, marketers, partners, and non-profits across industries including tech and SaaS, ecommerce, financial services, travel, and media. Pricing is usage-based on verification volume, with a free tier of 100 verifications and custom quotes for high-volume needs. The platform is GDPR-compliant and SOC II certified, with support in the US and EU.
