Clearout vs NeverBounce
Clearout and NeverBounce both keep their price figures out of a plain page read. Clearout's tiers live in a calculator, and NeverBounce's pricing pages refused every automated fetch in September 2026. So you can't settle this on a rate card. You settle it on what each does with the hard rows on your list and how each one sells you credits.
| Clearout | NeverBounce | |
|---|---|---|
| How you buy | Pay as you go, monthly or annual plans | Pay-as-you-go credits, or a subscription called Sync |
| Where the prices sit | A calculator on its pricing page | Pricing pages that blocked automated reads |
| Free credits | 100, no card | Free credits at signup, terms on its own site |
| Credit expiry | Never, and they roll over | Not stated on the pages we could reach |
| Unknown results | Returned to your balance | No billing rule on its readable docs |
| Accept-all domains | An attempt to resolve each one | Returned as catchall, 'Accept-all (Unverifiable)' |
| Accuracy claim | 99.73% | On pages that block automated reads |
| Security paperwork | Clearout holds ISO and SOC 2 Type II | Ask during your review |

Clearout strengths
- Clearout puts its effort into accept-all domains, the rows that stall most company lists. It attempts to resolve them instead of stopping at a label. Its credits never expire and roll over, and 100 free credits need no card. Form Guard checks addresses on your signup form as people type. Clearout holds ISO and SOC 2 Type II and publishes a 99.73% accuracy claim.
NeverBounce strengths
- NeverBounce keeps its output short and public. Its developer docs list five result codes: valid, invalid, disposable, catchall and unknown. A catchall carries the label 'Accept-all (Unverifiable)', so you know what you're holding. You can buy pay-as-you-go credits or subscribe through Sync, and it lists apps on Zapier and Make. Your engineers can scope the API from those docs before anyone books a call.
What separates Clearout from NeverBounce
Accept-all domains split these two more than any price could. Clearout tries to turn an accept-all row into a verdict using other signals. NeverBounce returns catchall and hands the call back to you. On a consumer list of Gmail and Outlook signups, that gap barely shows. On a company list it's the main event, because about 28% of a 10,000-address B2B benchmark sat on catch-all domains. What Accept-all (Unverifiable) means covers what to do with those rows.
Since neither prints a readable rate, get two written quotes at the same volume. Ask each one the same three things: the price per 1,000 at your size, whether an unknown result costs a credit, and when credits expire. Clearout answers the last two on its own pages, so its quote is the shorter conversation. The Clearout pricing breakdown and NeverBounce pricing show how each one structures its plans.
Your security review may decide it before price does. Clearout names ISO and SOC 2 Type II, which closes a vendor questionnaire quickly. For NeverBounce, send the questionnaire early and ask for its current reports. If your buyer is an engineer, NeverBounce's public result codes make a first integration easy to plan, and how an email validation API works walks through the same request cycle.
What Clearout and NeverBounce 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.
Questions about Clearout and NeverBounce
How much does Clearout cost compared with NeverBounce?
Neither figure could be read from a plain page in September 2026. Clearout's tiers sit in a calculator, and NeverBounce's pricing pages blocked automated reads. Ask both for a written quote at the same volume, then compare the price per 1,000.
Which one handles catch-all emails better?
Clearout attempts to resolve accept-all domains, while NeverBounce returns them as catchall, labelled 'Accept-all (Unverifiable)'. Clearout's result is an inference, because the server accepts every address. Treat both outputs as a risk grade rather than a confirmed mailbox.
Do Clearout credits expire?
No. Clearout credits never expire and roll over, per its own pages in September 2026. NeverBounce's expiry terms were not stated on the pages we could reach, so ask for them in writing.
What result codes does NeverBounce return?
NeverBounce returns five codes: valid, invalid, disposable, catchall and unknown, per its developer docs read on 24 September 2026. Unknown means the mail server could not be reached. Catchall means the domain accepts any address.
Pull 1,000 rows from your list and count the company domains. A high share points you at the accept-all question first. Then read Clearout vs ZeroBounce, the NeverBounce review and our pricing, or browse every head-to-head comparison.
