An imported list can contain subscribers while an activity finds no eligible recipients. Work through the checks below to establish whether the problem is with the import, the selected list or the activity's targeting.

Open the intended list under Subscribers and check whether the imported subscribers are present:

• Subscribers are present: check their contact details, subscription status and the activity's filters.
• Subscribers are missing: check the import results and destination list.

Work through these checks:

1. Destination: confirm the list name shown in the import and the list selected by the activity.
2. Completion: check that the import finished. If interrupted, supply the same unchanged file in the same browser and continue the saved import.
3. Mappings and usable identifiers: map an available Email, Phone or External ID, or Subscriber ID when enabled. For an email activity, check that the relevant subscribers have usable email addresses.
4. Results: inspect Created, Updated, Unchanged, Duplicate, Skipped and Errors counts. Download the error report for rows that were rejected or skipped.
5. Subscription status and targeting: importing someone does not clear an existing unsubscribe or invalid status. Check whether the activity excludes them because of their status, selected partitions or target expression.

For example:

• A Phone-only import can succeed, but those customers have no email address available for an email activity.
• A subscriber can have an email address and still be globally unsubscribed.
