What Suppression list means
A suppression list contains contacts or identifiers that a system must exclude from specified calls, messages, campaigns, or workflows.
Entries can come from opt-outs, company-specific do-not-call requests, national or state registries, wrong-party reports, legal restrictions, invalid contact data, complaints, fraud controls, or internal policy. The list should preserve scope and reason rather than only a blocked flag.
How it works
Before an action, the workflowWorkflowA workflow is a defined sequence of steps, decisions, actions, delays, and outcomes used to complete a business process. normalizes the contact identifier and checks all applicable suppression sources. A match blocks or reroutes the action and records the decision. New suppressions propagate to every tool, vendor, import, and retry queue that could initiate contact.
Practical use cases
Blocking contacts who revoked consent
Excluding wrong-party phone numbers
Preventing a list import from reactivating DNC records
Suppression must be checked at send or dial time. A clean export can become stale before execution, and copied lists can bypass later changes.
