How to Limit Responses to a Dynamics 365 Customer Voice Survey Link
Question details
A user needs to distribute a survey via SMS using a general link while ensuring that each person is restricted to only one response.
- Product
- Dynamics 365 Customer Voice
- Device & OS
- not provided
- Scenario
- Distributing a general survey link over SMS to a broad audience and needing to enforce data integrity by preventing multiple submissions from the same user.
- Observed behavior
- The business wants the general SMS link to behave like individualized email invitations, where the system automatically restricts each participant to a single completed response.
Ensure your survey is configured to identify respondents, as the single-response limit cannot be enforced on fully anonymous surveys where user identities are not tracked.
Enable Single Response in Distribution Settings
Configure your survey's distribution settings to automatically restrict non-anonymous participants to one submission per person.
By default, general survey links allow respondents to submit answers multiple times. To change this behavior for SMS or general web links, you must adjust the participant rules in the distribution settings.
Log in to Dynamics 365 Customer Voice, open your specific project, and select the survey you want to modify.
Navigate to the 'Send' tab located at the top of the interface to manage your survey distribution methods.
On the right-hand side panel, click on 'Distribution settings' to reveal the advanced participant and response controls.
Scroll to the Participants section and toggle on the 'One response per person' option. This ensures users can only submit the survey once.
Save your changes and generate your general link for SMS distribution. The system will now restrict responses for identified users.

Frequently Asked Questions
Does the 'one response per person' setting work for anonymous surveys?
No. The system relies on identifying the respondent to enforce the limit. If a survey is completely anonymous, Dynamics 365 Customer Voice cannot track who has already submitted a response via a general link.
Can I track who responded when using a general SMS survey link?
Yes, provided the respondent authenticates (such as signing in) or their session is otherwise linked to a known contact record in your Dynamics 365 environment, allowing the system to identify them.
What should I do if respondents can still submit multiple times after enabling the setting?
First, verify that anonymous responses are disabled in your Distribution settings. If the issue persists despite correct configurations, seek advanced troubleshooting advice on the official Dynamics 365 Customer Voice community forum.
