Contactability Score
A rating of how reliably you can actually reach a contact, based on verification status across their channels.
Definition
A contactability score estimates how likely you are to successfully reach a person, combining signals like whether their email verified, whether their phone is active and the right line type, recency of the data, and channel coverage. It helps prioritize the contacts most worth your outreach budget. Trackyr derives contactability from verification results so a list can be sorted by who's genuinely reachable, not just who has a listed address.
