Kickbox

Kickbox is an email verification platform. Users either upload a list for bulk cleaning or connect an API that checks addresses as people type them. The vendor says over 150,000 senders use it, and that it has verified more than 26 billion addresses.

What Kickbox offers

• List cleanup — sorts addresses into safe, role-based, invalid and mistyped groups.
• Real-time verification — blocks fake or mistyped emails on web forms, apps and point-of-sale.
• Integrations — imports from common email service providers and marketing tools.
• Deliverability consulting — audits and guidance on inbox placement problems.
