Bouncer vs Kickbox

Both vendors print their prices, and both keep unresolved addresses off your bill, so this choice turns on what sits around the verdict. Bouncer is an EU-based verifier whose credits never expire. Kickbox grew out of deliverability consulting and grades every address with its Sendex score.

Where each one is stronger

What each vendor does that the other does not, stated as capability rather than advice.

Bouncer strengths

  • Bouncer's ladder runs $8 for 1,000, $60 for 10,000, $400 for 100,000 and $2,000 for a million, read on their pricing page in September 2026. You can buy a big pack for the price break and draw it down for years, because the credits never expire. Duplicates and unknowns cost nothing. Their toxicity check flags domains with a risky history, and the EU base answers a data-residency clause in one line.

Kickbox strengths

  • Kickbox lets you start small: $5 buys 500 checks and $10 buys 1,000, with $70 for 10,000 and $500 for 100,000. The Sendex score grades how good an address is, so you can rank a list instead of only filtering it. Kickbox charges only for definitive results and refunds unknowns. Their terms carry a 95% deliverability guarantee, and they ban purchased lists, which tells you who they built it for.

What separates Bouncer from Kickbox

Expiry is the gap you'll feel first. Kickbox credits expire one year from purchase, and Bouncer's never do. If you verify a signup stream every month, you'll use a Kickbox pack well inside the year and the clock never bites. If you clean a large list twice a year, a million-credit pack has to be spent in twelve months at Kickbox, while the same pack can sit in a Bouncer account. Our credit expiry answer lists which vendors run a clock.

On price the two ladders cross. Kickbox is cheaper to start, at $5 for 500 checks. From 10,000 up, Bouncer's tiers came in lower at every rung we read: $60 against $70, $400 against $500, and $2,000 against $2,999 for a million. Since both vendors leave unresolved rows off the bill, the headline tier is close to what you'll really pay at either one.

The extra signal differs in kind. Sendex grades the single address, which helps when you want to send to the strongest half of a list first. Bouncer's toxicity check reads the domain's past instead. Neither changes what happens on an accept-all domain, where every probe gets the same success code, and neither prints an accuracy percentage, so you're comparing terms you can check on their own pages.

What Bouncer and Kickbox both run into

Vendor accuracy percentages in this category count how often a returned verdict was right. They are calculated after the catch-alls and the servers that refuse to answer have left the denominator. Hunter tested 15 verifiers on 3,000 real business addresses (3 November 2025) and measured 31.2% to 70.0% overall. Both kinds of figure are real and they are not measuring the same thing.

Questions about Bouncer and Kickbox

Which is cheaper, Bouncer or Kickbox?

At 500 checks Kickbox is, at $5. From 10,000 checks up, Bouncer's published tiers are lower: $60 against $70 at 10,000 and $400 against $500 at 100,000, read in September 2026. Weigh expiry too, since Kickbox credits last one year and Bouncer's never expire.

Do Bouncer and Kickbox charge for unknown results?

No. Bouncer never bills duplicates or unknowns, and Kickbox charges only for definitive results and refunds unknowns. That puts both among the vendors whose headline price is close to the real cost of a clean.

What is the Kickbox Sendex score?

Sendex is Kickbox's quality grade for an address, given on top of the valid or invalid verdict. You can use it to rank a list and send to the best addresses first. Bouncer's toxicity check rates the domain's history instead of the single address.

Does either vendor publish an accuracy rate?

Neither does, as of September 2026. Kickbox's terms carry a 95% deliverability guarantee, which is a promise about delivery and not a measured accuracy figure. Run the same 1,000 addresses through both and count the rows that came back unresolved.

Check how often you verify. Monthly or more, set the Kickbox pricing breakdown beside Bouncer's pricing at your volume. Twice a year or less, the one-year expiry settles it before the rate does. Every pairing sits on the comparison hub, and how verification works explains the verdicts behind both.
