The short answer
Kickbox cut its prices in 2026. It’s still a premium-priced verifier ($70 for 10,000 emails and $500 for 100,000, versus $400 for NeverBounce and Bouncer), but it’s now cheaper than ZeroBounce at every size from 10,000 up. What you pay for is a strong real-time API and the Sendex score, which rates how likely each address is to engage rather than just whether it exists.
How Kickbox pricing works
- Pay-as-you-go only. No subscriptions or monthly fees; buy credits when you need them.
- Steady volume discounts: $0.01/email up to 5,000, $0.007 at 10,000, $0.006 at 25,000, $0.005 at 100,000, about $0.0044 at 250,000, and about $0.003 at 1,000,000 ($2,999).
- A 750,000 tier ($2,400) sits between the 500K and 1M packs.
- One balance for bulk and API. Real-time signup checks and list uploads draw from the same credits.
When Kickbox is worth paying for
- You’re verifying signups in real time and want a fast, well-documented API.
- You need a per-address confidence score (Sendex) to decide what to do with catch-all and risky addresses instead of a flat “unknown”.
- Your volume is low enough that the absolute cost difference is small.
When to pick something cheaper
- Bulk list cleaning: EmailListVerify costs $186 for 100,000 emails and MillionVerifier $149, vs Kickbox’s $500.
- A well-known vendor at mid-range prices: NeverBounce is $400 for 100,000 and includes 1,000 free credits.
