A focused ZeroBounce alternative for developers.
Choose emailverifier.dev when you need a small verification API inside your product. Choose ZeroBounce when list cleaning, email scoring, inbox testing, blacklist monitoring, or enterprise support belong in the same platform.

What your budget is paying for
ZeroBounce publishes an entry purchase of $39 for 2,000 validation credits and bundles verification into a much wider deliverability platform. emailverifier.dev charges $10 for 20,000 checks because it does not include list uploads, scoring, inbox tests, monitoring, or managed enterprise services. The lower price is useful only if the focused API is the product you actually need.

Choose emailverifier.dev when
- You want 20,000 non-expiring checks for a one-time $10 purchase.
- You need one compact response for signup, trial, lead-form, or CRM decisions.
- You want each project to have its own API key, credits, and usage.
- You want the same verification tools available through REST and MCP.
Choose ZeroBounce when
- You regularly upload and clean large email lists.
- You need inbox placement, blacklist monitoring, email scoring, or broader deliverability tools.
- You need enterprise onboarding, account management, or published compliance certifications.
- You prefer detailed provider-specific statuses over a smaller application-facing contract.
Migration checklist
- 1Replace the ZeroBounce validation URL with POST /api/v1/verify.
- 2Move the API credential to the X-API-Key or Authorization header.
- 3Map valid decisions to deliverable, confirmed failures to undeliverable, and policy risks to risky.
- 4Handle unknown separately instead of treating it as deliverable or failed.
- 5Use flagged for a simple review-or-block branch, then inspect status when your policy needs more control.
Test your real integration.
Start with 1,000 credits. Keep ZeroBounce running until your status mapping and fallback policy behave as expected.
