Slack NPS Survey Example – Customer Feedback Questionnaire

Slack uses a branded customer feedback questionnaire to measure Net Promoter Score (NPS) and understand the customer experience. The communication introduces a named marketing leader, explains that the survey contains only two questions, and promises completion in under 60 seconds—clear friction-reduction techniques designed to improve response rates. Its central 0–10 recommendation question captures customer loyalty, while the “not likely” to “very likely” scale makes the action immediately understandable. The message also reassures respondents that every response will be read, helping build trust and positioning the survey as a meaningful product and customer experience feedback channel rather than a generic research request.
