Denylist

How to manage the phone number denylist for survey campaigns.

The Denylist is a global list of phone numbers that must not be contacted in survey campaigns. When a number is on the denylist, it is automatically excluded from outgoing calls regardless of which recipient list or campaign it appears in.

Common reasons a number ends up on the denylist include a recipient requesting removal during a call, a rejected call, or a manual decision by an operator.

Navigate toSurveys → Denylist.


Denylist entries

Each entry stores the following information:

FieldDescription

Removal request sourcesCampaigns that triggered an automatic removal request for this number, with the timestamp of each request.
