✓ Where RocketVerifier wins

  • RocketVerifier resolves a majority of catch-all addresses to a confidence-scored, send-safe verdict instead of leaving them "unknown" — MillionVerifier does not attempt this.
  • Every verification ships an evidence trail (syntax, MX, SMTP, catch-all confidence) instead of a single score.
  • RocketShield real-time form widget and continuous SPF/DKIM/DMARC monitoring are included.
  • Native MCP server for AI agents.

✓ Where MillionVerifier wins

  • MillionVerifier is genuinely cheaper at every published tier we checked: $39 vs $49 at 10K, $149 vs $269 at 100K, $449 vs $1,149 at 1M.
  • Simple, single-product focus with no subscription tiers to evaluate.
  • Fast bulk processing for very large one-off list cleans.

Best for: Price-sensitive, one-off bulk cleans where you don't care about getting a verdict on catch-all domains. If your list skews B2B (where catch-all domains are common), the price difference can be offset by how many addresses MillionVerifier leaves as an uncharged, un-actionable "unknown."

Migration

Moving from MillionVerifier

Send an email, get back a status and a score. Map the fields, run a sample, then point the integration at RocketVerifier.

1

Get an API key

Dashboard, then API Keys. A sandbox key (rv_test_...) lets you wire the integration before spending credits.

2

Map the response fields

The status field is deliverable, undeliverable, risky, or unknown. Map that onto the branching you already have.

3

Run a sample first

Re-check a list you already verified and compare the verdicts before you switch the whole flow.

4

Swap the endpoint

Point Zapier, n8n, HubSpot, or a direct API call at RocketVerifier, then retire the old key.

FAQ

MillionVerifier vs RocketVerifier FAQ

Is RocketVerifier cheaper than MillionVerifier?

No — MillionVerifier is cheaper at every tier we checked: $39 vs $49 for 10,000 credits, $149 vs $269 for 100,000, and $449 vs $1,149 for 1,000,000. Choose RocketVerifier when you specifically need catch-all resolution, an evidence trail, RocketShield, or a native MCP server — those are the actual trade-offs, not price.

What does "catch-all resolution" actually mean, and why does MillionVerifier skip it?

A catch-all domain accepts mail to any address, so a standard SMTP check can't tell whether a specific mailbox exists. MillionVerifier marks these "unknown" and doesn't charge for them — which avoids billing you for an ambiguous result, but also means you get no actionable verdict. RocketVerifier combines naming-pattern plausibility, domain reputation, and historical signals to resolve a confidence-scored verdict for most catch-all addresses instead.
