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:
| Field | Description |
|---|---|
| Phone number | The blocked phone number in international format (e.g.+36301234567). |
| Added at | The date and time the entry was created. |
| Reason | An optional note explaining why the number was added. |
| Removal request sources | Campaigns that triggered an automatic removal request for this number, with the timestamp of each request. |
