Clearout strengths

Clearout spends its effort on the rows most checks leave as a label. It attempts to resolve accept-all domains, which is where company lists get stuck. Its credits never expire and roll over, so a pack bought in spring still works next year. You get 100 free credits with no card, Form Guard to check signups as people type, and ISO and SOC 2 Type II for procurement.

Kickbox strengths

Kickbox prints its whole ladder: $5 for 500, $10 for 1,000, $70 for 10,000, $500 for 100,000 and $2,999 for a million, read on kickbox.com on 24 September 2026. It bills only definitive results and refunds unknowns. The Sendex score rates each address on quality, so you can send to the strongest rows first. Their terms add a 95% deliverability guarantee.

What separates Clearout from Kickbox

Sendex and accept-all resolution answer different problems. A Sendex score lets you rank a list and hold back the weakest part of it. Clearout's accept-all work tries to turn a label into a verdict on company domains. If your list is mostly consumer addresses, the score does more for you. If it's mostly company addresses, the accept-all pass does. Our catch-all glossary entry explains why those domains are hard for everyone.

Expiry turns the price ladder into a timing question. Kickbox credits last one year from purchase, so the $500 pack for 100,000 is best bought close to the job. Clearout's credits never expire and roll over, which suits a team that cleans twice a year and wants to buy once. The Kickbox pricing breakdown lays out each tier.

Read the list rules before you upload. Kickbox's terms ban purchased lists, so a file from a data provider needs a different home there. If your data comes from sign-ups and your own CRM, that rule won't touch you. Check Clearout's terms against your sources the same way, and see Kickbox vs ZeroBounce for how Kickbox fares against a suite.

What Clearout 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.
