Credential jobs want to confirm the address can still recover or access the account. The use case decides how much unknown you can tolerate, because a campaign can wait a day for an unknown to resolve, and a recovery path cannot. Amazon Email Checker is the ZelNum page that supports this job: Amazon Email Checker.
Quick answer
Read the export by use case. Reach jobs (campaign, CRM, support) can tolerate unknown rows with a retry. Credential jobs (account recovery, store binding, verification) cannot: a broken recovery path is the fastest way to lose access. The same status means different things in each frame.
The two uses
| Use | The question | Tolerance for unknown |
|---|---|---|
| Reach | Can we contact this person? | High. Unknown can retry and wait. |
| Credential | Can this address recover the account? | Low. Unknown must go to review now. |
The divide is the point. A campaign list can absorb unknowns and re-check them next week. An account-contact list cannot, because the row is the recovery path.
Use cases in practice
- Campaign prep. Registered emails on clean domains go to the send list; risky domains get suppressed; unknowns wait for a retry.
- CRM hygiene. Invalid and obsolete rows get retired with the reason logged, so nobody re-imports them next quarter.
- Account review. A seller store’s email that moved to risky domain is a flag. The recovery path is now in doubt, and that is an action, not a statistic.
- Verification readiness. Before a reset or a store update, the check answers one question: is the email on file still trustworthy?
Decision rules
| Status | Reach use | Credential use |
|---|---|---|
| Registered, clean domain | Usable. | Usable, verify the account side. |
| Risky domain | Suppress. | Repair or replace before the account depends on it. |
| Unknown | Retry in a day. | Review now. |
| Invalid | Suppress. | Replace the recovery path. |
Mistakes to avoid
- Running one threshold for every use case. A campaign can wait on unknowns; a recovery path cannot. The threshold belongs to the use case.
- Treating “registered” as proof of ownership. The address exists; who controls it is a separate question.
- Suppressing the unknown rows everywhere. On a campaign list, unknown is a queue. On an account list, it is a review item. The difference is the use case.
FAQ
What is the main use case for an Amazon email checker?
It depends on the use. Reach jobs want deliverability; credential jobs want recovery-path health. The same export serves both, read differently.
Why does unknown tolerance differ by use case?
Because the cost of waiting is different. A campaign can retry an unknown next week. A recovery path that waits is a lockout, and the difference is the use case.
What is a risky domain in an Amazon context?
A typo variant, a throwaway service, or a dead zone that passes format checks. It looks valid, it will not be read, and it should land in review for credential rows.
How often should I re-check?
Quarterly as a baseline, and before any account change or bulk send.
Does the check prove account standing?
No. It reports what the email signal shows. Account standing lives in Amazon’s own data.
