LOOKUP / RECIPIENT INTELLIGENCE

# Know the destination. Choose the next step.

Choose the evidence your next decision needs. Inspect a phone number or one email address, then keep quality, possession and consent distinct.

## Two recipients. Different questions.

Illustrative evidence for one signup. Neither result proves possession or consent.

### Phone routing evidence

The mobile example has unavailable roaming. One answered baseline remains useful; missing roaming is not false and adds no roaming property charge. Inconclusive classification remains unresolved rather than invalid.

### Email address quality

A favorable address verdict does not establish possession, consent or freedom from suppression. A typo suggestion belongs to the customer; inspect again after a change. A neutral result does not confirm the mailbox.

Choose phone intelligence or email address quality for the supported signup and implementation guide. Changing that destination does not run a lookup. These are fixed examples, not account or network reads.

LOOKUP / EVIDENCE FOR YOUR NEXT STEP

## Choose by the decision.

Request only evidence you can use. A paid result can be negative or unresolved.

### Choose a phone route.

Use network and coarse line type; request any of six optional properties only if they change your application decision. Confirm coverage and handle a missing answer.

### Assess one address.

Use result and integer confidence together. A typo is a suggestion for the customer; a neutral or future verdict needs an explicit policy. Check one email address per request.

### Check possession separately.

Quality, consent and identity answer different questions. Use a supported code flow when the pending action needs proof of access to the destination.

Evidence with its limits.

DOCUMENTED OPERATING BEHAVIOR

## An answer. A deliberate next step.

The maintained Lookup guides distinguish the baseline, independently answered properties and one email verdict. An unavailable property can leave the baseline useful; a negative answered verdict can still be billed.
