Kickbox

Kickbox is an email verification and deliverability platform that gives senders the insights they need to reach the inbox. Our email verification tool identifies and removes toxic or risky email addresses on your list by identifying deliverable, undeliverable, mistyped, disposable, and other problematic email addresses in your database. Verify email addresses in real-time with the Kickbox API. Sign up forms, newsletter opt-ins, and pop-up forms all can leverage our API to prevent fake, misspelled, or spammy emails from being submitted to your database.

Our email deliverability tool gives you insights that mailbox providers like Gmail do not: helps you know where your emails are landing (inbox, spam, promotions, etc), the health of your sender reputation, and health of your authentication setup.
