A Kickbox alternative with no clock on the credits
A third cheaper at every size, in euros, and nothing that has to be spent within a year.
The prices, side by side
Kickbox's published price table against ListCheckup's packs. Kickbox sells in dollars, ListCheckup in euros; no conversion is applied, and both exclude any applicable tax.
A year to spend is a clock. Never is a promise.
The year on the clock
Kickbox's pricing page says nothing about expiry. Its help centre answers the question directly:
"…you have one year to use the purchased credits."
Buy 25,000 credits for a 12,000-address list and the remainder has twelve months to be useful. ListCheckup credits never expire — leftover credits are the re-check before the next campaign, whenever that is.
Where the two agree
Unknown results are refunded at both services. Kickbox's pricing page says it plainly — if a result cannot be settled, the credit comes back — and ListCheckup keeps the same promise. That honesty is worth crediting, and it narrows the comparison to price, currency, and the clock above.
The free tiers
Kickbox gives the first 100 verifications free, once. ListCheckup gives 100 free verifications that refill back to 100 at the start of every month, no card required — the same hundred, every month instead of once.
When Kickbox is the better buy
Kickbox comes from the deliverability world, and if you want sender-reputation tooling from the same vendor as your verifier — with a US company's support behind it — that pedigree is real and ListCheckup does not compete with it. If what you need is the check, $150 against €55 for the same 25,000 answers is the comparison that is left.
The European difference
ListCheckup prices in euros — no dollar conversion on your card — and the servers that hold and check your list are in the European Union, with a data processing agreement on request.
Where this leaves you
A third cheaper at every size, no clock on the credits, and a free hundred every month against a first hundred once. Create your account and the free hundred is yours today.
