What does NeverBounce do?
- Returns five result codes: valid (0), invalid (1), disposable (2), accept all or unverifiable (3) and unknown (4), as text or integers in the API.
- Prices pay-as-you-go credits from $8 per 1,000 down to $4,000 for 2,000,000, with credits expiring 12 months after purchase.
- Runs Sync on the Growth plan ($49 a month for up to 10,000 emails), re-verifying CRM and email platform lists daily, weekly or monthly and charging only for new, unique emails.
- Publishes sending guidance per code: accept-all addresses bounce at about half your list's invalid rate, so send them in small, monitored batches if your provider requires under 4% bounces.
- Adds GTM Guard, aimed at giving AI agents clean inputs, and lists 80+ integrations including HubSpot, Salesforce, Pipedrive, Zapier and n8n.
- Fixes common typos (gmai to gmail), returns the company name from each email and cleans up to 10 lists at once on pay-as-you-go.
Where does NeverBounce fit in a GTM engineering stack?
NeverBounce is the pre-send verification step in a GTM engineering stack: it checks the email each Clay waterfall returns, and its Sync keeps the CRM list clean after the campaign.
- 1A Clay waterfall of finders, such as Hunter then Prospeo, returns one email per contact
- 2Validate Email with NeverBounce tags each row valid, invalid, disposable, accept-all or unknown
- 3Valid rows push to lemlist or Smartlead; invalid and disposable rows stop there
- 4Accept-all rows go to a small, monitored campaign; unknowns are re-verified first

Who is NeverBounce best for?
A good fit if you
- Teams that want CRM lists kept clean automatically, since Sync re-verifies contacts in HubSpot, Salesforce or Pipedrive on a schedule.
- Builders who wire verification into n8n or Zapier flows, both listed as NeverBounce integrations with n8n workflow blueprints.
- Teams that want clear send rules for catch-alls, given NeverBounce's documented guidance on accept-all and unknown results.
Look elsewhere if you
- Occasional users who buy credits in bulk and use them slowly, because pay-as-you-go credits expire 12 months after purchase.
- Clay users who want to verify on Clay credits: Clay's NeverBounce action requires your own NeverBounce account.
- Teams that need definitive answers on catch-all domains; NeverBounce returns them as accept all (unverifiable) rather than resolving each mailbox.

NeverBounce FAQs
Do NeverBounce credits expire?
Yes. NeverBounce's pricing page says pay-as-you-go credits expire 12 months after purchase. The Growth subscription works differently, covering a monthly verification volume instead.
Should I send to accept-all emails NeverBounce returns?
NeverBounce says accept-all addresses are often valid and bounce at about half your list's invalid rate. If your sending provider requires a bounce rate under 4%, it advises sending to them selectively: trusted sources, small segmented batches and close bounce monitoring.
What does an unknown result mean in NeverBounce?
Unknown means the mail server did not answer in time, often because of greylisting or a security gateway. NeverBounce says it is not a negative result and that re-verifying later usually returns a definitive answer.
Can I use NeverBounce in Clay?
Yes. Clay has a Clay-built Validate Email with NeverBounce action on all plans. You need your own NeverBounce account, so verifications draw on your NeverBounce credits rather than Clay credits.
Who owns NeverBounce?
NeverBounce's site footer lists ZoomInfo Technologies LLC, so ZoomInfo is the operating company. NeverBounce still has its own pricing, API keys and help centre at neverbounce.com.
