ZeroBounce pricing, explained
You've probably seen ZeroBounce's $39 figure and want to know what it buys. It buys 2,000 credits, and those credits sit inside a deliverability suite. Here's how the pay-as-you-go floor, the ONE plan and the billing rules add up, read on zerobounce.net in September 2026.
| What you're buying | ZeroBounce | ZapBounce |
|---|---|---|
| Entry purchase | $39 for 2,000 credits, the minimum | $5 for 1,000, no minimum |
| Subscription | ONE plan from $99 a month; 20% off annual, 15% off with autopay | Monthly plan at 15% less than the same credits pay-as-you-go |
| Free allowance | 100 checks a month, recurring | 100 checks a month, recurring, no card |
| Credit life | Subscription credits roll over while the plan is active; no pay-as-you-go expiry rule on the pricing page | Credits never expire |
| Unknown results | Free | Never billed |
| Catch-all results | Use a credit | One credit, labelled catch_all |
| Duplicate rows | No rule on the pricing page | Never billed |
| Also in the price | Inbox placement testing, blacklist monitoring, DMARC tooling, activity data | Coverage reported on every file |
ZeroBounce figures read on zerobounce.net/pricing and its free verifier page on 24 September 2026; the suite list read on zerobounce.net on 18 September 2026. ZapBounce figures are from our own pricing page. Confirm ZeroBounce's current prices on their site before you buy.
The $39 floor buys 2,000 credits
ZeroBounce's pay-as-you-go entry is $39, and it's also the minimum: 2,000 credits in one purchase. That's about two cents an address. If you clean a few hundred addresses at a time, from an event list or a form export, most of that pack waits for the next job.
ZapBounce starts at $5 for 1,000 checks with no minimum, then $25 for 10,000 and $139 for 100,000. You can see how the rest of the market prices a check in our cost of verification answer.
ZeroBounce ONE and the subscription discounts
ZeroBounce ONE is the subscription route, from $99 a month. The pricing page lists 20% off for annual billing and 15% off with autopay. Subscription credits roll over while the plan stays active, so a quiet month doesn't cost you the balance.
That roll-over is tied to the plan staying active, and the pricing page gives no expiry rule for pay-as-you-go credits. ZapBounce credits never expire, on a plan or off it. Our monthly plan costs 15% less than the same credits bought pay-as-you-go, and unused credits roll over. Why that matters for an occasional cleaner is in why credits should never expire.
Unknowns are free, catch-alls cost a credit
ZeroBounce doesn't charge for unknown results, which is now the norm: 8 of 13 vendors with readable pricing skip that charge, by our count on 24 September 2026. Catch-all results do use a credit at ZeroBounce.
ZapBounce bills the same way. One probe to a random address at the same domain shows whether it accepts everything, the row comes back catch_all, and it costs one credit. Unknowns and duplicate rows are never billed. In one 10,000-address B2B benchmark, about 28% of addresses sat on catch-all domains, so this rule moves your real cost more than any tier does.
What the suite adds to every tier
ZeroBounce prices verification inside a wider product. The same account covers inbox placement testing, blacklist monitoring on your sending IP, DMARC tooling and activity data on recent engagement. You pay for that breadth in every tier, whether or not your team opens those tabs.
So price it in two parts. List the suite tools your team used last quarter; those are costs worth keeping. Then take the verification spend on its own: add up a year of invoices and divide by the addresses you checked. That per-address figure is the one to set beside a published ladder.
Running a fair price test
Take 1,000 addresses you've already mailed, where you know which ones bounced. Run 100 of them through ZeroBounce's free monthly allowance, and the full file through ZapBounce's 100 free checks plus a $5 pack. Compare each tool's calls against your real bounces, and count how many rows got a definite verdict.
ZapBounce prints that share, its coverage, on every file. For the product side by side, read ZapBounce vs ZeroBounce, or see the wider field on ZeroBounce alternatives and the comparisons hub.
What ZeroBounce gets right and wrong on price
Both columns are required here. A page that only fills one is an advertisement wearing a review's clothes.
Where ZeroBounce is genuinely good
- Unknown results are free, so an address nobody could resolve costs nothing.
- The free allowance of 100 checks renews every month instead of once at signup.
- Subscription credits roll over while the ONE plan stays active.
- Inbox placement testing, blacklist monitoring, DMARC tooling and activity data come in the same account.
Where ZeroBounce falls short
- Pay-as-you-go starts with a 2,000-credit minimum at $39, about two cents an address.
- The pricing page gives no expiry rule for pay-as-you-go credits.
- Roll-over depends on the subscription staying active.
- The suite is priced into every tier, used or not.
