Every ZeroBounce plan
ZeroBounce sells verification either as one-time pay-as-you-go credit packs (from $39 for 2,000) or as the ZeroBounce ONE subscription, which is its only and minimum subscription and carries the bundled deliverability tools (placement, warmup, blacklist, DMARC monitoring). The old credit-only monthly tiers are retired: the pricing page now offers Freemium, Pay-As-You-Go and ONE, plus a custom ONE plan builder for higher volumes. Prices and ONE inclusions come from ZeroBounce's own pricing page and its Product and FAQPage schemas.

What it includes
Freemium

100 email verification/scoring credits, 1 inbox placement test, 1 email server test, 1 blacklist monitor (scanned every 24 hours) and 10 Email Finder searches per month (resets monthly, business or premium domain required), no credit card. No access to warmup or DMARC monitoring. Free standalone deliverability checker tools.
Pay-as-you-go (entry)
$39 one-time for 2,000 credits
2,000 verification credits ($0.0195/email). Larger packs lower the rate ($69 for 5,000, about $0.0138/email; $129 for 10,000, about $0.0129/email). Credits never expire while a ZeroBounce ONE subscription is active; without one, expiration rules may apply.
Entry pay-as-you-go price per ZeroBounce's own pricing page and its Pay-As-You-Go Product schema (2K $39, 5K $69, 10K $129, 25K $274, 50K $499, 100K $649, 250K $1,299, 500K $2,199).
Monthly verification subscription
From $18/mo for 2,000 credits
Monthly email verification credits that replenish each month at a discount to pay-as-you-go. Higher tiers scale credit volume.
Entry monthly tier reported at $18/mo for 2,000 credits by third-party pricing roundups (mailfloss, usebouncer); some roundups cite higher tiers. ZeroBounce surfaces ONE as its main subscription.
ZeroBounce ONE
$99/mo ($79/mo billed annually)
10,000 validation credits, 100 inbox placement tests, 250 warmup seeds, 10 blacklist monitors, 1 DMARC monitor domain, 100 email server tests, 10,000 email finder searches per month; 15% off additional credits.
Official ZeroBounce ONE page lists 10,000 credits at $99/mo and states 10,000 as the minimum; annual billing is charged once at $948/yr, which ZeroBounce quotes as $79/mo, a 20% discount. Unused tests, monitors, searches and warmup seeds do not roll over; credits do.
What the same job costs at Unspam
Unspam charges for tests rather than for seats or mailboxes, so the comparison with ZeroBounce depends on how much you send and how often you check.
