DeBounce vs MillionVerifier
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedDeBounce compared with MillionVerifier
The two cheapest general-purpose verifiers here, and they diverge on exactly one point. MillionVerifier resolves 30 to 40 percent of catch-alls inside a standard credit and charges nothing at all for risky results; DeBounce charges ten credits for a catch-all validation. DeBounce is slightly cheaper at 100,000 ($135 against $149) and considerably more expensive at a million ($750 against $449). For consumer lists DeBounce's documented guarantee makes it the more reassuring buy; for B2B lists MillionVerifier's credit policy wins outright.
MillionVerifier compared with DeBounce
DeBounce is the nearest competitor on both price and philosophy: $135 for 100,000 and $750 for a million against MillionVerifier's $149 and $449, with a detailed 97.5 percent deliverability guarantee that pays out in graded credits. The differences are that DeBounce charges 10 credits for a catch-all validation where MillionVerifier includes it, and MillionVerifier gets much cheaper above half a million. Take DeBounce for its documented guarantee mechanics and richer feature list; take MillionVerifier for large volumes and free risky results.

Cost-conscious email marketers, WordPress and ecommerce operators, and small agencies that want cheap bulk cleaning plus real-time form protection from a vendor that documents exactly what it guarantees and what it does not.
Choose MillionVerifier if
Cost-sensitive email marketers, agencies, and outbound teams cleaning lists in the tens of thousands to millions, who want the lowest defensible cost per usable answer and do not need certifications, a deliverability suite, or a large vendor behind them.

Strengths and limitations
DeBounce
Strengths
- Among the cheapest published ladders in the category: $25 per 10,000, $135 per 100,000, $750 per million, and roughly $0.00044 per check at five million.
- Every feature is available at every volume, with no plans, tiers, or capability gating, and API access carries no separate fee.
- The most thoroughly documented guarantee among the low-cost vendors: 97.5 percent overall, 95 percent on Microsoft accounts, 98 percent elsewhere, with graded credit remedies and a full refund above 8 percent bounces.
- Unusually honest about failure modes, naming the exact domains and account types where results will be poor rather than burying them in a support article.
Limitations
- Catch-all validation at ten credits per address undermines the cheap headline rate on exactly the lists where verification matters most.
- No security certifications: no SOC 2, no ISO 27001, no trust centre, no penetration test summary.
- The company is small, founded in 2018 with a lean team and no disclosed funding, which is a concentration risk for a service in your sending path.
- Named exclusions are honest but real: GMX and WEB.de may produce more than 10 percent bounces, and free.fr, orange.fr, sfr.fr, comcast.net, and att.net will produce heavy unknowns.
MillionVerifier
Strengths
- The cheapest published ladder among the general-purpose verifiers here: $39 per 10,000, $149 per 100,000, $449 per million, falling to $0.00017 per address at fifty million.
- Charges nothing for risky results, including unresolved catch-alls, which is the most generous billing policy in the category and materially lowers the real cost on B2B lists.
- Built-in catch-all resolution converts 30 to 40 percent of accept-all addresses into definite verdicts inside the normal pass, with no premium credit and no separate workflow.
- A plainly worded money-back guarantee: exceed 4 percent hard bounce after cleaning and the last payment is refunded, with the vendor explicitly claiming no small print.
Limitations
- No published security certifications at all: no SOC 2, no ISO 27001, no trust centre, no penetration test summary, no data residency statement.
- Public sources put the team at roughly four people, which is a real concentration risk for a service sitting in the path of your sending programme.
- No deliverability suite: no inbox placement testing, no blacklist monitoring, no DMARC reporting, no warmup, so this is one tool among several rather than a consolidation play.
- Catch-all resolution at 30 to 40 percent is a fraction of what BounceBan claims, so a list that lives or dies on the accept-all bucket may still need a specialist.
Pricing compared
DeBounce
Prepaid credits only, on a published volume ladder with no expiry, no contracts, and no setup fees. Different operations consume different numbers of credits.
- Small volumes$15 to $75
- Mid volumes$135 to $450
- Large volumes$750 to $2,200
For consumer and mixed lists, DeBounce is close to the best value in the category: $135 to clean 100,000 addresses against $400 at Bouncer and $649 at ZeroBounce, with every feature included at every volume and a guarantee documented down to the arithmetic. The picture changes on B2B data. At ten credits per catch-all validation, a list that is 30 percent accept-all costs roughly $0.0045 per address at the 100,000 rung once you verify that segment properly, which lands it above BounceBan and well above MillionVerifier, both of which handle catch-alls inside a standard credit. Work out your accept-all share first; it decides whether DeBounce is the cheapest option you have or a false economy.
MillionVerifier
Prepaid credits only, sold as one-time packages on a published volume ladder, with no subscription, no contract, and no expiry. Billing applies to good and bad results only.
- Starter volumes$39 to $89
- Growth volumes$149 to $449
- Bulk volumes$799 to $8,499
On raw cost per usable answer, nothing in this comparison set beats MillionVerifier. Cleaning 100,000 addresses costs $149 against $400 at Bouncer, $649 at ZeroBounce, and $300 at BounceBan, and the not-charging-for-risky rule means the real bill on a B2B list is lower still. Add the 10 percent auto top-up bonus and the arithmetic gets slightly absurd. What you give up is everything that is not verification: no compliance evidence, no deliverability suite, no enterprise relationship, no meaningful vendor scale. For an email marketer or agency whose success metric is a clean list and a low bill, this is the correct default. For anyone whose success metric includes surviving a security questionnaire, it is not an option at any price.
Editorial verdict on each
DeBounce
DeBounce is a cheap verifier that behaves like an expensive one in the way that matters most: it tells you exactly what it promises, exactly what it pays if it misses, and exactly which addresses it will handle badly. The published ladder down to roughly $0.00044 per check, every feature available at every volume, non-expiring credits, a WordPress plugin, a real-time widget, daily list monitoring, and forty-plus payment methods make it an obvious candidate for small businesses cleaning consumer or mixed lists. The catch, and it is a specific one, is the ten-credit catch-all validation, which flips the economics on B2B data and pushes serious accept-all work toward MillionVerifier or BounceBan. Check your accept-all share, read the named exclusions, and if neither disqualifies you, this is one of the best-value purchases in the category.

Best ValueMillionVerifier wins the argument it chose to have. On cost per usable answer it is the cheapest credible verifier here, and the two policies behind that, never charging for risky results and resolving 30 to 40 percent of catch-alls inside a standard credit, matter more on a real B2B list than the headline rate does. Add non-expiring credits, a 10 percent auto top-up bonus, and a money-back guarantee written in one sentence, and the value case against ZeroBounce or NeverBounce is not close. The counterweight is everything the company chose not to build: no certifications, no trust centre, no residency commitment, no deliverability suite, and roughly four people behind the whole operation. If you are an email marketer, agency, or outbound team cleaning lists and answering to nobody's security questionnaire, buy this and spend the savings on sending. If your procurement process has a checklist, this will not clear it, and you should not pretend otherwise.
