Note

When importing reachability events to Optimizely Data Platform (ODP), you must use the customer's messaging identifier for which you want to update the reachability status. For example, if you want to update the reachability status for an email, you must use that email as the identifier in your reachability event. For more information about identifiers in ODP, see our developer documentation.

Reachability may impact attempts to send marketing campaigns to the identifier. If noted as unreachable, certain marketing services or channels may skip the identifier, even when qualified for the campaign. This endpoint generates events of type reachability and action reachable or unreachable.
