How it works
From a list to a clear next step.
FairValid keeps your source rows connected to the answers, so you can review what changed and choose what to do next.
Bring your addresses
Start with one address, upload a CSV or choose contacts from a connected source.
Review before checking
Inspect the selected rows and the credits that may be reserved.
Run the check
Track progress while FairValid processes selected addresses.
Use the results
Filter, compare and export the outcome with your original row identity.
What each outcome means
| Outcome | Meaning | Credit effect |
|---|---|---|
| Valid | The check returned a usable positive result. Delivery is never guaranteed. | 1 credit |
| Invalid | The address did not pass the check. | 1 credit |
| Catch-all | The domain may accept many addresses; interpret with care. | 0 credits |
| Unknown | The check could not reach a dependable answer. | 0 credits |
| Still checking | The selected address has no final result yet. | No final charge yet |
Technical failures and unprocessed work have no net charge. Reservations for those items are released or returned.
