[ Book a call ](/book)[ See case studies ](/case-studies) 05 ## 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. ## Related [![](/_astro/neverbounce.BMIMci8P_1Sa9px.webp)NeverBounce API review](/tool-directory/verification/neverbounce)[![](/_astro/zerobounce.DMK7iQt0_27Oa23.webp)ZeroBounce API review](/tool-directory/verification/zerobounce)[![](/_astro/bouncer.36eXjmET_Z1goo1l.webp)![](/_astro/neverbounce.BMIMci8P_1Sa9px.webp)Bouncer vs NeverBounce](/tool-directory/compare/bouncer-vs-neverbounce)[![](/_astro/leadmagic.VYwz4sDG.svg)![](/_astro/zerobounce.DMK7iQt0_27Oa23.webp)LeadMagic vs ZeroBounce](/tool-directory/compare/leadmagic-vs-zerobounce)[![](/_astro/millionverifier.CykZd8HV_Z1yyzSe.webp)![](/_astro/zerobounce.DMK7iQt0_27Oa23.webp)MillionVerifier vs ZeroBounce](/tool-directory/compare/millionverifier-vs-zerobounce) Read from [neverbounce.com/pricing](https://neverbounce.com/pricing), [zerobounce.net/pricing](https://www.zerobounce.net/pricing) and each tool's API docs.
