Every record carries who released it and when, so the question of where a contact came from always has an answer.
When someone asks where you got their details, RelationLens records answer it: which employee released the contact, and when.
When an employee removes a contact permanently, it is deleted for good and never raised again from that mailbox.
Fewer manual privacy requests is estimated at about $27,400 a year for a company with $100 million in revenue. See RelationLens.
