+ = . Bounceless vs MillionVerifier: an honest comparison
MillionVerifier is refreshingly blunt: buy a pack of credits, keep them forever, and pay one credit whether an address is clean or a catch-all its engine had to chase. That plain-dealing is the whole pitch, and for occasional bulk cleans it holds up. The question this page asks back, just as plainly, is what that one credit buys you: a status word from their engine, or a reason-coded confidence level that Bounceless resolves into a send, review, or suppress call.
MillionVerifier keeps it plain: buy credits once, keep them forever, pay the same single credit for a catch-all as for a clean check, and lean on a real money-back guarantee for risky emails that Bounceless does not match. At the larger packs its per-credit rate runs below ours. Bounceless answers with the shape of the result rather than the price of it: every check returns a confidence level, the reason codes behind it, and a send, review, or suppress call, with Catch-All Evidence on the hard B2B domains, Doorman on the roadmap, blacklist, and inbox monitoring on the roadmap, and MCP access for AI agents. The trade is a cheap status label against a decision made for you.
How we score: one point per round. Price rounds are computed from dated public figures; feature rounds show their verdict on the row, so every point is auditable.
Feature-by-feature, sourced
Every MillionVerifier row below links to the public source it came from, or says "Not publicly disclosed" instead of guessing. One point per round: a tie means both products cover it, rounds without public information score nothing, and any price rounds in the Pricing band below count toward the same score.

| Feature | Bounceless | MillionVerifier | Round |
|---|---|---|---|
| What a single result carries | You get a confidence level and the reason codes behind it right on the result itself, so a policy sorts on the score instead of picking apart a bare status word | The documented API returns a quality label and a status such as ok, catch_all, invalid, or unknown plus a result code, but no numeric confidence scoresource | [ BOUNCELESS ] |
| Pre-send recommendation (send / review / suppress) | Built in, no extra step: the Pre-Send Decision takes that confidence level together with its reason codes and hands you one call, send, review, or suppress, the moment you export | Not publicly disclosed | [ BOUNCELESS ] |
| Catch-all address handling | Catch-All Evidence runs premium deep catch-all domain detection billed at five credits fresh or three if already cached on the tough B2B accept-all domains and hands back a scored confidence with reason codes, not a lazy round-up to valid | An advanced SMTP process the vendor markets as resolving a share of accept-all domains into definite results, delivered as a plain valid or invalid label with no score behind itsource | [ BOUNCELESS ] |
| Billing for unknown and unresolved catch-all results | Not billed, plain and simple: an unresolved check stays unresolved, the confidence level drops, and no credit gets spent forcing a guess | Its catch-all page states it does not charge credits for a result that comes back Unknown or an unresolved Catch-Allsource | [ TIE ] |
| Credit expiration | Buy a credit and it is yours for good, no clock running on it | Its pricing section states purchased credits never expiresource | [ TIE ] |
| Bulk list verification | Upload through the dashboard and you get the same result contract the API gives, so a list you eyeball reads no different from one a script pulled | Uploads as a TXT, CSV, or XLSX file or copy-paste, with a documented bulk API for upload, status, and downloadsource | [ TIE ] |
| Named platform integrations | Our hub walks through six named platforms, Mailchimp, HubSpot, SendGrid, ActiveCampaign, Mailgun, and AWeber, and everything else connects through the REST API or MCP instead | A ready-made ESP and CRM connector list its integrations page names one by one, wider than the six guides on the Bounceless hub (14 named integrations)source | [ MILLIONVERIFIER ] |
| Money-back guarantee on results | We do not cut a refund check: a lowered confidence level and its reason code take the place of money coming back | A money-back guarantee on risky emails, refunding for any address it cannot verify with certaintysource | [ MILLIONVERIFIER ] |
| Real-time signup-form gating | Doorman signup-form gating is on the roadmap — not a shipped product surface today | Markets the same protection through its sub-second real-time API rather than a packaged drop-in widgetsource | [ TIE ] |
| Blacklist monitoring and inbox placement | Blacklist watch on the roadmap and inbox-placement monitoring on the roadmap are on the roadmap alongside verification — not shipped as platform defaults today | No blacklist or inbox-placement monitoring is published; its EverClean re-verifies connected lists every week, stripping bad addresses, list hygiene rather than deliverability watchsource | [ BOUNCELESS ] |

What we won’t guess
Pricing, honestly
For MillionVerifier the same single credit is billed whether a check returns clean or a catch-all its engine resolved, and an unresolved result is not charged, so its sticker is its effective rate.
The two packs land on the same price at this size, the point where the ladders cross.
MillionVerifier's per-credit rate stays below ours here and holds that lead through the packs above.
This is the largest pack Bounceless publishes; MillionVerifier lists still-bigger tiers above it, so open the source to compare past this point.
Bounceless renews its free credits every month; MillionVerifier grants its free credits once at signup.
Beyond the table
MillionVerifier makes a blunt promise and keeps it: buy a pack of credits, use them whenever you like, and pay one credit per check whether the address is clean or a catch-all its engine had to chase. There is no metering to decode, no surcharge for the hard cases, and no expiry clock. For a team that cleans a big list once in a while, that plainness is worth real money, and the pricing table on this page says so at the tiers where it is true.
Bluntness is also where the product stops. What comes back from a MillionVerifier check is a status word and a quality label. There is no score behind it to sort on and no recommendation stacked on top, so whether to send, hold, or drop an address stays with you and your own thresholds. On a clean consumer list that is often fine. On a messy business list full of accept-all domains and role addresses, the tool tells you what it found and leaves the hard calls where it found them.
Bounceless draws the line one step further in. Every check returns a confidence level, the reason codes that produced it, and a Pre-Send Decision that reads both and stamps send, review, or suppress on the export, so the call is made rather than deferred. The hardest case gets its own machinery: Catch-All Evidence puts the B2B accept-all domains, the spot where catch-all setups genuinely turn up, through premium deep catch-all domain detection billed at five credits fresh or three if already cached, and comes back with a graded confidence instead of a flat valid-or-not. MillionVerifier charges you the same single credit to attempt that resolution, which is genuinely fair pricing; the difference is that it hands back a label and Bounceless hands back a reason.
The blunt-docs comparison runs the same way. MillionVerifier documents a clean real-time API and a straightforward bulk one, and it is honest about not charging for a result it cannot resolve, the same policy Bounceless holds. But the platform around the verification is where the two diverge. Doorman on the roadmap would gate a signup form as a ready-made product where MillionVerifier points you at its raw API to build the same guard yourself. Blacklist watch on the roadmap and inbox placement are on the roadmap where MillionVerifier offers weekly list re-checks and nothing that watches your sending reputation. And an MCP server plus agent skills hand the whole verdict to AI agent directly, a surface MillionVerifier does not describe.
So the honest read is a plain one. Where the job is a cheap, fast, occasional bulk clean and your team is content owning the send-or-suppress call, MillionVerifier is a strong, well-priced buy, and it wins real rounds above the crossover, on its guarantee, and on its longer connector list. Where the job is a continuous pipeline that would rather receive a decision than a label, price a hard catch-all the same but explain it, and let agents read the verdict without glue code, that is the line where blunt stops being enough and Bounceless starts.

Is Bounceless a drop-in replacement for MillionVerifier?
For the verification step, yes, with one mapping decision. MillionVerifier hands back a result and a quality label; Bounceless returns a confidence level with reason codes, so a workflow that branches on MillionVerifier's status values needs a short policy update rather than a rewrite. The adjacent pieces move over too: its real-time API guarding a signup form maps to Doorman on the roadmap, and its EverClean list re-checks give way to blacklist and inbox monitoring on the roadmap for the platform. The one thing with no Bounceless equivalent is the money-back guarantee.
When is MillionVerifier actually cheaper than Bounceless?
Past the crossover marked in the pricing table above: from the mid tier upward its per-credit rate slips below the matching Bounceless pack and keeps that lead through its biggest published packs. Because MillionVerifier charges the same single credit for a catch-all as for a clean check, its sticker rate is also its effective rate, so the comparison is a straight per-credit read rather than a metering puzzle. Run your own volume against both before deciding.
What does MillionVerifier's money-back guarantee actually cover?
Per its own pages, MillionVerifier refunds credits for risky emails and for any address it cannot verify with certainty. It is a genuine, checkable commitment and one Bounceless does not match with a refund promise. Bounceless takes the other route: instead of paying you back after a bad address slips through, it lowers the confidence level and attaches a reason code so the risky address can be held back before the send, not compensated after it.
Can AI agents use Bounceless directly?
Yes. Bounceless is built AI-native: an MCP server and agent skills put verification straight in front of an agent, which reads the confidence level, reason codes, and the send, review, or suppress call as a first-class response, nothing to translate out of a status field. Whether the job at hand is lead intake or a list cleanup pass, the agent works straight off that verdict. MillionVerifier does not describe a comparable agent surface anywhere in its public materials, which is why that row sits marked not disclosed rather than guessed at.
Does Bounceless charge for uncertain results the way MillionVerifier does not?
Neither side bills for a result it cannot resolve. MillionVerifier states it does not charge for an Unknown or an unresolved Catch-All, and Bounceless treats an unresolved check the same way: no forced verdict and no credit spent. The difference sits in what you get back on the checks that do resolve. MillionVerifier returns a status label; Bounceless returns a scored confidence level with the reason codes that produced it, so a sending policy can treat probably-fine and genuinely-unclear differently.
Why does this page not compare accuracy numbers?
Because MillionVerifier's accuracy figure is self-reported, measured on its own lists under its own conditions, and nobody has raced the two engines on one list. Quoting that number as if it settled anything would be spin, so the link goes to their page and the figure stays their claim, plainly labeled. Bounceless would rather show its reason codes and let you run both tools on your list than trade unverifiable percentages.
Is Bounceless a good MillionVerifier alternative for signup forms?
For verification and Pre-Send Decision, yes. MillionVerifier markets signup-form protection through its real-time API, so you wire the check into the form yourself. Doorman on the roadmap signup-form gating and deliverability monitoring on the roadmap are on the roadmap — not a shipped packaged product today. If a fast API you assemble yourself is what you want, MillionVerifier covers that shape; treat Doorman on the roadmap as a planned adjacent surface rather than a platform default you can buy now.
