Kickbox costs $10.00 per 1,000 on a 500 pack, falling to $3.00 at 1,000,000, pay as you go with no subscription. Credits and balances at Kickbox do not transfer.
Who this is for
People who are re-evaluating Kickbox for one of the reasons below. If none of them applies, there is no reason to move.
- Price at volume. Kickbox lists a $70 pack for 10,000 addresses and $500 for 100,000, and credits are bought per pass.
- Unknown results are refunded as credits, which helps, but each new list is still a new purchase.

Step 1: export your results from Kickbox
- When the list shows Ready and Complete, click Download.
- The CSV has each address and its result (deliverable, undeliverable, risky or unknown). Keep the result column.
We could not find Kickbox's own help page for downloads, so this follows a third-party guide that may be out of date.

Step 2: sort the statuses you already paid for
Drop the file into the verification results cleaner. It maps each status to send, retest or remove, keeps your other columns and gives you a CSV for each. It runs in the browser and needs no account. Nothing you already paid for is re-verified unless you choose to.
Step 3: re-check the rest on SimpleVerifier
The unconfirmed rows (catch-all, risky, unknown) are the ones worth a second opinion. Upload them at /verify; the first 100 are free. Confirmed mailboxes come back valid, anything we cannot confirm comes back risky, never valid.

On Starter and Growth unused emails do not roll over; a plan is a monthly allowance, not prepaid credit. For your own pattern use the cost calculator. Where Kickbox is cheaper for your size, the table says so.

Common questions
- How do I move my Kickbox results to SimpleVerifier?
- Export the finished list from Kickbox as a CSV with its result column, drop it into the free verification results cleaner to sort every status into send, retest or remove, then upload the addresses you want re-checked to SimpleVerifier. Statuses the cleaner does not recognise are listed, never guessed.
- Do I lose anything by leaving Kickbox?
- Possibly. Kickbox says it is SOC II certified and GDPR-compliant, with verification and support in both the US and the EU. Unknown results are refunded as credits. Pick Kickbox if you need a vendor with published SOC II certification or deliverability consulting from the same team.
- Will my unused Kickbox credits transfer?
- No. Credits and balances stay with Kickbox; SimpleVerifier cannot import them. Check Kickbox's own pricing page and terms for what happens to an unused balance.
- Is SimpleVerifier more accurate than Kickbox?
- We have not benchmarked the two, so this page makes no accuracy claim. Anything SimpleVerifier cannot confirm is returned as risky, never valid. Re-check a sample, including addresses you know are dead, and compare.
- Can I try it before I pay?
- Yes. Sign in with Google and the first 100 email checks are free, with no card. Plans then start at $9 a month, monthly only, cancel anytime.
