# Kickbox: Pricing, Features & Alternatives

Kickbox verifies addresses through a clean API and bulk uploads and returns a Sendex score, its own estimate of how likely an address is to engage, alongside the usual deliverable, undeliverable and risky results. It offers ESP integrations and a real-time Kickbox Open check for signup forms. New accounts get 100 free verifications; pay-as-you-go starts at $5 for 500 per 2026 trackers, which disagree at larger tiers ($70 or $80 for 10,000). Its site blocks automated reads, so confirm the current grid before budgeting.
