## Frequently asked questions

### Does valid email syntax prove delivery?

No. Syntax checks do not prove mailbox existence, ownership, deliverability, or consent.

### Does a postal lookup verify the whole address?

No. It provides regional context or a candidate code; full address verification is separate.

### Does a valid tracking number prove movement?

No. Carrier scans and shipment status are needed to prove movement.
