Kickbox returns more than a valid or invalid verdict: its Sendex score rates the quality of a deliverable address on factors such as domain reputation and whether it looks like a real person, which helps decide whether a technically valid address is worth mailing.
It flags disposable providers, role accounts and accept-all domains, offers a real-time API for signup forms, and provides deliverability tooling and expert consultation for senders with reputation problems. Pricing is per verification with no subscription requirement.
Best suited to: senders who want quality scoring alongside validity, and teams working through an existing deliverability or reputation issue.
Listed pricing is indicative. Final cost depends on seats, contract term and add-ons — request a quote for exact numbers.
Low-cost bulk verification with non-expiring credits and a bounce guarantee.
