Pricing
Pay-as-you-go. Same product at every tier.
Nine pack sizes from $4 for 1,000 credits to $750 for a million. Bigger packs just drop the per-email rate. No subscriptions, no credit expiry, no tier behind a sales call.
The full ladder
Nine packs. One product. No quote tiers.
Every pack unlocks the same verification pipeline. The only thing that changes between tiers is the size of the bundle and the per-email rate. Use the interactive slider on the home page if you want to dial in by list size.

Pricing FAQs
- Do credits expire?
- No. Buy 10,000 today, use them next year. Same balance.
- What does one credit get me?
- One credit = one verification, regardless of result. We bill per check, not per valid result.
- What if a verification is wrong?
- If we return Valid for an address and the actual send hard-bounces within 72 hours, the credit is returned to your account balance. Forward the bounce to support@getkillbounce.com — we credit it within five business days. The refund is in credits, not cash; you do not get to cancel a pack for a money refund. The full mechanics are in the refund policy.
- Can I refund a pack I bought?
- No. Pack purchases are non-refundable. Once a pack is paid for, the money is not returned — the credits are yours to use whenever, with no expiry. There is no 24-hour cooling-off window, no change-of-mind refund. Pay only when you are sure.
- Why are the bigger tiers cheaper per email?
- Verification cost is mostly variable (SMTP probes against external providers). Buying capacity in larger blocks lets us amortize fixed overhead — we pass that through. There are no hidden tier privileges; the only thing a bigger pack changes is the per-email rate.
- How do I pay?
- Cards (Visa, Mastercard, Amex) via Dodo Payments, our merchant of record. Dodo issues the legal payment receipt; KillBounce sends a branded confirmation with your new balance.
- Is there a free trial?
- Every new account gets 100 free credits — enough to run a small list end-to-end. No card required, no upgrade nag.
- What about over a million addresses?
- The largest published pack is 1,000,000 credits at $750. If you need more, email sales@getkillbounce.com — we will scope it directly. We are not running a fake-quote tier; we just have not productized higher SKUs yet.
