Side by side
How they compare
What matters when you choose a verifier.

| Reason with each result | A statusMessage sentence on every result | A short reason with a numeric code (for example Accept-All, code 4) |
| Catch-all addresses | Flagged Risky within the normal credit. No paid step to resolve them | Flagged Accept-All. Optional catch-all validation at 10 credits per address |
| Addresses the server won't confirm | Processing first, then the final result. If the server never confirms: Risky (status no_response), one credit used | Checked up to 3 times before Unknown is returned. Whether Unknown is charged isn't stated |
