Comparison
MillionVerifier vs ZeroBounce: which email verifier fits?
MillionVerifier sells credit packs that never expire, from $39 for 10,000 ($0.0039 each) to $8,499 for 50 million, and currently does not bill catch-all or unknown results under a goodwill programme it can withdraw. ZeroBounce costs more per check, from $39 for 2,000 pay as you go or $99 a month for 10,000, but adds AI catch-all scoring, published rate limits, an MCP server and SOC 2 Type 2.
Pick MillionVerifier if
- Price per email decides it: $0.0039 at 10,000 and $0.00044 at 1 million
- You verify in bursts and want credits that never expire
Pick ZeroBounce if
- You want to score catch-alls rather than drop them, with AI scoring at 1 extra credit
- You need published rate limits, for example 80,000 validations per 10 seconds

Which one to pick
Choose MillionVerifier if
- Price per email decides it: $0.0039 at 10,000 and $0.00044 at 1 million.
- You verify in bursts and want credits that never expire.
- Your lists hold many catch-alls, and today those results are not billed.
- You only need a simple GET call or a CSV upload.
Choose ZeroBounce if
- You want to score catch-alls rather than drop them, with AI scoring at 1 extra credit.
- You need published rate limits, for example 80,000 validations per 10 seconds.
- You need EU-only or US-only processing.
- Procurement asks for SOC 2 Type 2 or ISO 27001.
- You want an MCP server so an AI agent can validate addresses.
If neither fits: A verifier only tells you whether a mailbox accepts mail, not whether it belongs to the person you want. Find and match the right person first, then verify.
