Which one to pick
Choose NeverBounce if
- You clean lists now and then and want the lowest one-off price: from US$8 for 1,000 credits and US$0.002 a credit at 2 million.
- You run large bulk jobs with a callback when each job finishes.
- You want a free bounce-rate estimate for a list before spending credits.
- You want to verify at sign-up with a JavaScript widget.
Choose ZeroBounce if
- You verify every month: ZeroBounce ONE credits roll over while you stay subscribed.
- You do not want to pay for unknown results: ZeroBounce never charges for them.
- You need catch-all scoring, or a published SOC 2 Type 2 and ISO 27001 programme.
- You want an AI agent to verify emails through an official MCP server.
If neither fits: If you also need to find the emails, an email finder that verifies as it finds can remove a step. See the email verification guide for every route.

Questions people ask
Which is cheaper, NeverBounce or ZeroBounce?
On one-off packs, NeverBounce: 10,000 credits cost US$50 against US$129 on ZeroBounce Pay-As-You-Go, and 1 million cost US$2,500 against US$3,199. On a subscription, ZeroBounce ONE gives 10,000 credits a month for US$99 (US$79 billed annually) and NeverBounce Growth up to 10,000 emails a month for US$49. Prices verified 25 Oct 2026.
Do NeverBounce or ZeroBounce credits expire?
NeverBounce pay-as-you-go credits expire 12 months after purchase. ZeroBounce credits never expire while you have an active ZeroBounce ONE subscription; without one, expiry rules may apply depending on when the credits were bought or granted.
Do they charge for unknown results?
ZeroBounce says it never charges for unknown results or for removing duplicates. NeverBounce does not charge for duplicates or bad syntax; its pricing page does not say how unknown results are billed.
Can I verify emails for free?
Both give a small free allowance. NeverBounce gives 10 free credits when you sign up with a business email, plus a free list analysis. ZeroBounce's Freemium plan gives 100 validation credits a month to signups with a business or premium domain.
Do NeverBounce and ZeroBounce work with AI agents?
ZeroBounce publishes an official open-source MCP server (@zerobounce/mcp on npm) that an agent can use to validate emails and check credits. NeverBounce has no MCP server in its docs, so an agent would call its REST API directly.
