Where they pull apart

BillionVerify

Stands out: Hosted MCP at mcp.billionverify.com plus bulk and real-time API on every paid path.

Watch out: New monthly subscriptions prepay three months at checkout. Unused metered credits do not roll like a cash balance. Catch-all still needs human judgment.

Not the right fit for

  • Buyers who refuse a three-month monthly prepay
  • Anyone needing phone or LinkedIn enrichment

ZeroBounce

Stands out: Validation plus quality scoring on one meter, with a real free 100-credit allowance and a public $99/month subscription.

Watch out: Pay-as-you-go starts at $39 for 2,000 validations if you do not want a subscription. Heavy lists will burn the 10,000-credit ONE cap.

Not the right fit for

  • Teams that needed a finder, not a verifier
  • High-volume senders who will outgrow 10k/month immediately

Pros and cons

BillionVerify

  • 600 free credits a month, plus daily login bonus
  • Hosted MCP endpoint and REST API
  • One-time packs from $20 for 20k credits
  • Monthly plans prepay the first three months
  • No phone or company-enrichment product
  • Unused metered credits do not roll over

ZeroBounce

  • Public $99/mo ONE plan for 10k validations
  • 100 free credits, no trial needed
  • API plus MCP
  • ONE's 10k cap is easy to blow on a big agency list
  • Does not find emails, only validates them
  • Pay-as-you-go $39 pack is easy to miss if you only look at $99
