Audiences define who a campaign may call. Contacts are the individual people or phone numbers in those audiences. Do-not-contact lists, also called DNC or DND groups, define numbers that must not receive calls.

​
Create a group

1

Start a contact group

Open Audiences or Contacts, start an upload, enter a name, and choose whether the file supplies callable contacts or suppression entries.
2

Choose a source

Download the template when you need the expected file shape. Upload one .csv, .xlsx, or .xls file up to 21 MB, or import contacts from a connected HubSpot or Salesforce account.
3

Review validation

Review the valid, invalid, and duplicate number counts. Persistence excludes invalid and duplicate numbers when you save the group.
4

Save the group

Save the processed group, then select it when you configure a campaign audience.
Use a DNC or DND suppression list for numbers that must not receive campaign calls. Review suppression coverage before every launch.
You can replace the uploaded list or edit the group name and type. Check campaigns that use the group before you delete it. Open a group to review entries and their metadata. A saved group can be ready while individual numbers remain active or blocked.
