-: Bounceless vs MailDB: an honest comparison
MailDB wore its promise in the suffix: a database of mail, email addresses turned into rows you could look up. Give it a domain and it returned a company's contacts; give it a name and an employer and it returned one person's address, a query against the open web dressed as a table lookup. That query still resolves today, but not to a database. Type maildb.io now and it forwards to an online-gambling page, the name repurposed by whoever grabbed the domain after the finder went dark. This page is for the searcher who ran the old lookup and got a slot advert back.
MailDB is not a tool you can weigh today. It was an email discovery platform, a lookup that turned a domain into a company roster or a name into one address, with verification attached as a smaller feature, and it has gone dark: maildb.io now redirects to an unrelated online-gambling page, with no successor named. To generate contacts, a running finder is the tool. To vet a list already in hand, Bounceless is the live option: it scores each address, shows the reason codes behind the score, and issues one call to send, review, or suppress, with Doorman on the roadmap and reputation monitoring on the roadmap, and native agent access in the one product.
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. 10 rounds found a gambling redirect instead of a live product to score against and scored nothing.
Feature-by-feature, sourced
Every MailDB 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 | MailDB | Round |
|---|---|---|---|
| A verifier you can query today | Doorman on the roadmap and deliverability monitoring on the roadmap (blacklist / inbox placement) are on the roadmap — not shipped platform surfaces today | Gone: maildb.io returns a permanent redirect to an unrelated online-gambling page, and no MailDB email product remains to sign up forsource | [ BOUNCELESS ] |
| Where the old lookup lands now | On a working account: type the address and Bounceless starts checking, the destination rather than a stop on the way to one | On a slot advert: the name forwards to a gambling landing page with no connection to email, the domain repurposed after the finder went darksource | [ NOT SCORED ] |
| What MailDB actually was | A verifier, never a directory: it grades an address you bring, it does not go fetch one you lack | An email discovery platform first: Domain Search pulled a company roster from a domain, Person Search pulled one professional address from a name, with list verification riding alongsidesource | [ NOT SCORED ] |
| Finding versus judging an address | The judging half done properly: each address returns a score, the codes that explain it, and one send, review, or suppress instruction | The finding half was the point: MailDB sourced contacts from public pages and networks, and a returned address arrived as a record to use, not a verdict to trustsource | [ NOT SCORED ] |
| Published pricing today | Every rate sits in the open: buy-once packs alongside recurring plans, each tier showing its number, with a free monthly grant to trial first | None: the domain redirects to spam and quotes nothing, its old rate card left no readable trace in the archive, and the retired bounceless.io page marked its plan prices unrevealedsource | [ NOT SCORED ] |
| Confidence figure and reason codes per result | Fixed to every check: a score you can rank and set a threshold against, with the codes that produced it shown alongside | Nothing to grade here: a finder returned a contact record, not a per-address confidence you could rank or defend | [ NOT SCORED ] |
| Send, review, or suppress recommendation | The Pre-Send Decision turns the score and its codes into one printed instruction per exported row: send, review, or suppress | Never part of it: a discovery tool listed the addresses it found, it did not tell you which to trust before a send | [ NOT SCORED ] |
| Catch-all address handling | The accept-all business domains a bulk export waves through are stopped and appraised instead: Catch-All Evidence runs premium deep catch-all domain detection billed at five credits fresh or three if already cached and returns a graded confidence | Out of scope: a finder gathered addresses to use, it did not sit in judgement on accept-all domains | [ NOT SCORED ] |
| Real-time signup-form verification | Doorman signup-form gating is on the roadmap — a planned real-time form gate, not a shipped platform surface today | Out of scope: MailDB filled a database with addresses, it did not guard a form against them | [ NOT SCORED ] |
| Blacklist monitoring and inbox placement | Blacklist watch on the roadmap and inbox-placement tracking on the roadmap are on the roadmap — not a shipped bundle today | Out of scope: a discovery tool never watched a sender's blacklist exposure or inbox placement, and nothing runs to watch it now | [ NOT SCORED ] |
| AI-native access (MCP and agent skills) | Agents connect straight over an MCP server or packaged skills and read the finished contract whole, the score, its reasons, and the call, with no wrapper to build | Out of scope: a directory that no longer answers exposes no MCP server or agent surface to connect to | [ NOT SCORED ] |
Choose Bounceless if
- ✦The MailDB lookup now returns a gambling page instead of a contact, whereas bounceless.io returns a graded read on whatever address you type into it.
- ✦You would rather receive a decision than a data row: each result arrives as a confidence figure, its reason codes, and a flat send, review, or suppress verdict, not a record you still have to appraise.
- ✦You want form gating and monitoring planned beside verification, with agent access live today: Doorman on the roadmap and deliverability monitoring on the roadmap (blacklist / inbox placement) are on the roadmap; MCP access ships today.
- ✦The discovery side of the old routine needs its own tool regardless, so hand the checking side to something purpose-built for it rather than a directory whose lights are off.
Reach for a live email finder if
- ✦Your need is discovery, not verification: generating a company roster from a domain or one address from a name was MailDB's actual craft, and Bounceless does not do it, so a running finder in the related links is the right tool for that side of the work.
- ✦You are building a prospecting list from scratch at volume, sourcing many new contacts rather than scrutinising a handful you already hold: that is a finder gathering rows, not a verifier grading them one at a time.
- ✦You need to enrich thin records, attaching a job title, a phone, or an employer to a bare name, which is the fielded lookup MailDB ran and not a step Bounceless performs.
- ✦You are only chasing what became of the old bookmark: the domain redirects to a gambling page, and this record plus the archive are the paper trail MailDB left behind.
What we won’t guess
Pricing, honestly
Beyond the table
A name that ends in DB is making a database’s promise, and MailDB meant it literally: email addresses filed as rows you could query. The suffix told a marketer exactly what to expect. You handed it a key and it returned records. Give it a company domain and its Domain Search returned that company’s people; give it a name and an employer and its Person Search returned one working address, a search across the open web dressed up as a table lookup. Verification sat in the corner as a smaller switch. Finding was the whole point, and for a while the name earned it.
Then the lookup stopped returning what it promised. The clear product captures sit years back in the archive, and everything after thins out: an empty script shell, then a bare forward. Run the query now and the domain resolves, but not to a database. It forwards, permanently, to an online-gambling page, a slot and lottery advert in another language with nothing to do with email. The name that once looked up people now looks up a casino, with no goodbye note and no successor named, just a table that quietly emptied and a sign repurposed to sell something else.
That leaves a comparison with almost nothing solid on the other side, which is the honest place to start. No dashboard answers, no rate card posts, no result field survives, because the engine that did the finding is off and the domain that carried its name points at spam. The stray figures the old bounceless.io comparison once printed against MailDB do not help either: its plan prices were marked unrevealed, and the dollar tiers on the page were our own. So the only real service left to perform here is to set the ending down plainly and point past it to a verifier that still returns an answer.
The replacement is built to appraise an address, not to unearth one. Each check comes back already decided, its score attached, the codes that back that score listed under it, and a single instruction, send, review, or suppress, written onto the row before export. Accept-all business domains, the ones a discovery dump tends to pass along untouched, are pulled aside and read here, appraised by Catch-All Evidence, which runs premium deep catch-all domain detection billed at five credits fresh or three if already cached. Doorman on the roadmap would screen each address at the signup form on the roadmap and would refuse the risky ones on arrival; blacklist and inbox-placement monitoring on the roadmap are on the roadmap to keep the sending reputation in view from inside the same account — not shipped today — and an agent pulls the entire scored result off the MCP server with no connector in the middle. Discovery is not part of any of that, and the boundary is the point: MailDB filled a table with people, Bounceless renders a verdict on the ones already in yours. The old suffix promised a database you could query for addresses; what stands here is a judgement you can query for each of them, from a name that still resolves to a product.

+. Frequently asked questions
What happened to MailDB?
The email discovery tool switched off quietly. Its readable product pages sit years back in the Wayback record; after them the site decays into an empty script shell, and today the maildb.io address issues only a permanent forward to an unrelated gambling page. Nobody was appointed to carry the brand on, and the redirect leads nowhere useful, so anyone typing the name in now is effectively starting a fresh search for a replacement.
Was MailDB an email verification service?
Only as a side feature. MailDB sold itself as an email discovery platform: its Domain Search read a company's people out of a domain, and its Person Search read one professional's address out of a name, with list verification bolted on as a minor extra. The retired bounceless.io page dressed it up as a rival verifier and hung numbers on it (its table even rendered the name as MailBoxDb, if that is the spelling you remember), but those numbers were our own marketing lines rather than MailDB specifications, which is why none of them appear here as MailDB facts.
Why does maildb.io lead to a gambling site?
Because the domain outlived the product and was picked up afterward. When a small tool lapses, its expired domain is often grabbed by operators who point it at whatever monetizes stray traffic, here an online-slot and lottery page with no connection to email. The redirect is real and current, confirmed by direct request, and it means the MailDB name now advertises spam rather than any service. Treat the address as retired for good.
Is Bounceless a drop-in replacement for MailDB?
It replaces one of MailDB's two halves cleanly and not the other. The discovery half, producing addresses from a domain or a name, has no Bounceless counterpart, because Bounceless does not generate contacts at all. The checking half is where it slots in and then some: hand it an address already sitting in your list and it returns a confidence figure, the reason codes that produced it, and a send, review, or suppress call at export, in place of the thin verification switch MailDB kept in the corner. Anyone who leaned on MailDB only to sanity-check a finished list gets a fuller answer here.
Can Bounceless look up an address from a name or domain, the way MailDB did?
No. That was MailDB's headline act, and it is simply not something Bounceless does. Bounceless reads an address you supply and reports on it; it does not run a domain or a person's name through public sources to manufacture an address you did not already have. If your workflow depended on that lookup, the tool for it is a running finder, several of which sit in the related links. Bounceless picks the job up on the far side of discovery, once the addresses exist and the only open question is which of them are safe to mail.
How do I check a list I already exported from MailDB before it went dark?
Bring the file straight into Bounceless. The addresses MailDB once handed back are just rows now, and it makes no difference to the verifier where they came from: upload the list and each address returns a confidence figure, the reason codes behind it, and a send, review, or suppress call at export, so an old finder dump gets graded and de-risked before you mail it. That is the one half of MailDB's job Bounceless takes over cleanly, and it does not need the finder still running to do it, only the addresses you already saved.
Can AI agents use Bounceless directly?
Yes, and it is wired in from the start rather than added later. An agent reaches the verifier over the MCP server or through the packaged skills and gets structured output back directly: the confidence figure, the reason codes, and the send, review, or suppress call, with nothing to scrape and nothing to reassemble by hand. The neat mirror is in the register itself. MailDB let a caller query a table of contacts; Bounceless lets a caller query a verdict on each address, so an agent cleaning a list receives the decision rather than a row it must still grade for itself.
