DeBounce vs MillionVerifier
Both of these compete on price, and they get there in different ways. DeBounce posts the lowest headline rate in the category and bills harder checks as extra credits. MillionVerifier sells a flat commodity check at $449 for a million and refunds anything it couldn't verify with certainty.

Where each one is stronger
What each vendor does that the other does not, stated as capability rather than advice.
DeBounce strengths
- DeBounce starts from $0.00045 a check, with tiers running from 5,000 to 5,000,000 credits. Credits never expire, and 100 free credits get you started. Its catalogue of email platform connections is one of the widest in the category, so a clean can run where your list already lives. They also back results with a 97.5% deliverability guarantee, and they print their bulk speed: under 2 hours per 100,000, read in September 2026.
MillionVerifier strengths
- MillionVerifier keeps the maths flat. It charges $89 for 50,000 and $449 for a million, pay as you go, with no subscription to manage. Credits never expire, stated twice on their page, and 100 free credits need no card. Their risky-email refund returns the cost of any address they couldn't verify with certainty, which puts the price of doubt on them rather than on you.
What separates DeBounce from MillionVerifier
The headline rate and the invoice can differ a lot at DeBounce, and the gap depends on your list. A standard check costs one credit, catch-all validation costs ten and enrichment costs twenty. On a consumer list with few accept-all domains, the headline rate is close to what you pay. On a B2B file where a quarter of addresses sit on accept-all domains, the catch-all credits can multiply the bill several times over.
MillionVerifier removes that variable by charging one flat rate for every address, then refunding the ones it couldn't settle. A refund still means the vendor decides which rows qualify and when the money comes back, so check the credit note after each run. Their full package ladder sits behind a control on the homepage rather than on a pricing page, which makes it harder to quote from and easy to miss.
Their headline claims measure different things. DeBounce guarantees 97.5% deliverability on what it passes, and MillionVerifier claims 99%+ accuracy. Both describe results after the unresolvable addresses left the count. Hunter tested 15 verifiers on 3,000 real business addresses (3 November 2025) and measured 31.2% to 70.0% overall, which is the other side of the same arithmetic.
What DeBounce and MillionVerifier both run into
Vendor accuracy percentages in this category count how often a returned verdict was right. They are calculated after the catch-alls and the servers that refuse to answer have left the denominator. Hunter tested 15 verifiers on 3,000 real business addresses (3 November 2025) and measured 31.2% to 70.0% overall. Both kinds of figure are real and they are not measuring the same thing.
