How each one bills you
Kickbox charges $10.00 per 1,000 on a 500 pack, falling to $3.00 at 1,000,000, pay as you go with no subscription, metered as per-email fees, bought as credit packs. DeBounce charges $13.80 a month for 5,000 credits, or pay as you go from $3.00 per 1,000 on a 5,000 pack, falling to $0.44 at 5,000,000, metered as pay per email, or the same volumes monthly; pay-as-you-go credits never expire.
Kickbox's page does not say whether credits expire. DeBounce says its pay-as-you-go credits never expire. For uneven volume, expiry often matters more than the headline price, because credits that lapse raise the real cost of every address you did verify.
What to watch with Kickbox: verification is billed per email, so cleaning a large list is a variable cost you cannot forecast from the plan price. With DeBounce: every option is metered by the credit, so every pass over the list is billed again — the cost scales with how often you clean, not just how much.
Both meter verifications, so checking the same list again costs again. Before committing to either, verify an address you invented at a real domain and an address at a catch-all domain on both. The first should come back invalid and the second as risky or accept-all, not valid.
Choose Kickbox if
you want deliverability and sending-reputation advice from the vendor that verifies your list.
Disclosure — our product
Where SimpleVerifier fits, and where it does not
We publish this comparison and we sell a third option, so treat the rest of this section as the pitch it is. SimpleVerifier is a flat monthly price with unlimited email verifications and API access included, so there are no credits to buy or expire:
Pro $29.99/mo
Unlimited email verification, finder and phone format checks.
Email + Phone $49.99/mo
Everything in Pro, plus live carrier lookups for your phone lists.
That is worth it in two cases: large lists, because volume does not change the price, and lists you verify repeatedly, because a confirmed result is cached for 14 days so the second pass costs nothing. Outside those two cases, a metered vendor is usually cheaper and you should use one, Kickbox and DeBounce included.
