COMPARE:
BounceBan or NeverBounce for verifying a list
BounceBan against NeverBounce for verifying an email list before you send to it, with the same seven questions asked of each and neither one flattered. Mamba Labs builds Apify actors. Email Waterfall Orchestrator is ours, it is the third column, and it does not win most of these rows.
The short answer
NeverBounce cleans a big marketing list well and gives up on catch all domains. BounceBan is built for exactly the domains NeverBounce marks unknown.
Side by side
| BounceBan | NeverBounce | Email Waterfall Orchestrator | |
|---|---|---|---|
| What it actually does | Says whether an address will accept mail, including on the catch all domains other verifiers give up on. | Cleans an email list into valid, invalid, disposable, catch all and unknown buckets. | Calls a chain of email finders in the order you set and returns the first address that verifies. |
| Coverage and hit rate | Its whole argument is the catch all case, which is where most lists lose their unusable half. | Very high throughput on large files, with real time verification available on the same account. | As wide as the providers you put in it, because it is the chain rather than one provider. |
| What it costs | Credits per verified address, and it does not charge for an address it can only mark unknown. | Per verified address, priced in volume tiers, with pay as you go and monthly options. | A couple of cents per row on top of whatever your own provider keys cost. |
| How it fits a workflow | An API, a bulk upload, and a Chrome extension, with native steps in Clay and Make. | A mature API with native connectors into the big marketing platforms and CRMs. | One call per row from Clay or from a script, with the provider that answered named in the output. |
| Where the data comes from | Live SMTP conversation plus its own catch all inference, run per address at request time. | SMTP checks against the receiving server, plus its own list of known disposable and role domains. | Whichever provider answered, and it tells you which one did. |
| What it takes to set up | Upload a list or take the key. Minutes either way. | Upload a file and read the report. It is built for a marketer, not a developer. | Bring your own keys, set the order, run it. The keys are the work. |
| Where it stops | It verifies. It will not find you an address that does not exist yet. | Catch all domains come back as catch all, which leaves the decision back with you. | It buys nothing for you. With no provider keys it has nothing to call. |
The same seven questions are asked on every compare page here, in this order, so two of these pages can be read against each other.
What each is actually better at
- BounceBan wins on coverage and hit rate, what it costs. A verifier built to give a real verdict on catch all domains.
- NeverBounce wins on how it fits a workflow, what it takes to set up. An established verifier, now part of ZoomInfo, aimed at marketing list hygiene.
- Email Waterfall Orchestrator wins on where the data comes from. Runs several finders in order on your own keys, and stops at the first verified answer.
- Nobody wins on what it actually does, where it stops. BounceBan and NeverBounce give the same answer on those, and we are not going to invent a difference.
Where to get them
What is best for you
Look at what percentage of your list is catch all before you choose. On a consumer list it is small and NeverBounce is the more mature product with the better integrations. On a B2B list it is often a third of the file, and a third of your list marked unknown is not a cleaned list. That is the case BounceBan exists for, and it is the one most cold email lists are in. Whichever you use, verification is the last step and not a substitute for finding good addresses in the first place.
