Measuring NPS in the fintech industry serves as an indicator of customer satisfaction and loyalty. Fintech companies that make a real effort to up their customer experience game and boost their NPS scores are setting the stage for solid and long-lasting connections with their customers. It’s the secret sauce for success in the cutthroat fintech market – happy customers, happy business!

But here’s where it gets a bit tricky. The intricate dance between complex financial products, regulatory constraints, and the constant demand for seamless user experiences makes it hard to gauge customer satisfaction. 

For fintech companies, there’s a double duty – not only do they need to offer top-notch financial services, but they also have to keep their customer’s data safe. Regular surveys can sometimes mess with this delicate balance, risking the privacy of data. Striking the right chord between getting feedback and keeping things locked down is a real head-scratcher.

But, how to do that? Let’s find out!

The Fix – Personalized Unique Survey Links

Over the years of working with many Fintech companies, I have found that personalized unique links offer a cutting-edge solution to the challenges posed by traditional survey methods. 

These links, facilitated by advanced NPS software, act as secret doors to gather feedback without putting data at risk. Unlike generic surveys, these links are tailor-made for individual customers, ensuring a personalized and secure feedback collection process.

I have personally experienced some amazing benefits of these links while working with Fintech companies. Some of them are: 

Benefits of Using Personalized Unique Links in the Fintech Sector 

  • Enhanced data security: Using personalized unique links helped me mitigate the risks associated with traditional surveys as it directly addresses data security concerns. Each link is unique to the recipient, ensuring confidentiality. 
  • Increased response rates: The personalized nature of the links fosters a sense of importance and relevance for customers. This helped me to have higher engagement and increased response rates
  • Customization for targeted feedback: These links provide customization options. Using these links, I have customized survey questions based on individual user interactions and behaviors, yielding more specific and actionable insights. 
  • Accurate tracking of survey responses: The unique links facilitate precise tracking of responses, which allowed me to analyze feedback trends and implement targeted improvements.

Now, let’s dive into a real-time fintech case study on how it improved its NPS with these customized links.

Case Study: Fintech Success with Personalized Unique Link

The Challenge

A major Fintech company in India was facing the challenge of keeping its customer’s personal information secure while gathering feedback from them.  So, in a bid to ensure data security, all the while measuring and improving their NPS, they collaborated with SurveySensum.

The company had a large number of customers with sensitive personal data and they wanted to send NPS surveys to their customers in a bid to improve its NPS in Fintech. But their major concern was with the leak of sensitive personal data of its customers. If their customers can’t trust them with their personal data then it doesn’t reflect good on the company’s reputation.

The Solution – Step-By-Step Process

Now, in order to send surveys to them they were brainstorming solutions to keep the PII of these customers safe and secure. 

So, what’s the solution here? – Personalized Unique Survey Links.

1. They Imported Data Specific to Each Customer ID

Every company maintains a customer ID for each customer. This ID is mostly a randomly generated numeric string which is used as a primary key. The client made use of this numeric string and imported the data corresponding to each ID preventing the need for accessing PII outside the system.

Here’s how they executed this process:

  • They masked their customer IDs using the SurveySensum masking application.
  • These masked customer IDs were then uploaded to the SurveySensum system where unique survey links were generated and uploaded to the bank’s server.
  • Then these unique survey links were sent to the customer via the WhatsApp number that the customers were already familiar with.
  • The feedback was collected, analyzed, and displayed in the SurveySensum dashboard.

2. They Created Unique Survey Links

This led to the use of Personalised Unique Links, a feature that creates a unique and personalized link for every single customer. In SurveySensum’s survey builder, they used the option to create unique survey links of the same survey for different customers.

Here’s how unique survey links were created with SurveySensum:

  • Log in to SurveySensm
  • Create a survey
  • Click on ‘Share’
  • Now, select the ‘Unique Links’ option.
  • Here, upload the contact list, select the expiry date of the survey, and then click on ‘Generate Links’.

This GIF shows how SurveySensum provides the option to create unique survey links to send the same survey to different customers.

And the best part about this process is that SurveySensum has no knowledge of who the customer is: no Name or Email or Phone Number. This way, no PII data leaves the internal systems.

Here’s how customer ID is masked, keeping important data secure. 

The image shows the masked customer ID as seen by SurveySensum. The sheet shows no name or email ID of the customer - ensuring complete anonymity.

Once the responses are in, the client tracks the Customer ID (or masked ID) and all data associated with the customer that can help with the analysis and ultimately with closing the feedback loop with customers.

3. They Created Unique Survey Links 

They had an existing WhatsApp account which was already used for their support and general updates, so the customers were familiar with the number. Now, with the help of SurveySensum’s WhatsApp survey feature, they used this WhatsApp number to share these unique survey links.

The Result

Happy with the data integrity and safety, they started collecting transactional NPS feedback within the first 2 months with the help of unique survey links and API integrations using WhatsApp.

By identifying the most common issues on different touchpoints and closing the loop effectively with the help of instant detractor alerts, the client increases its NPS score by +15 points.


This extended case study underscores the power of sending personalized unique survey links to gather and improve NPS in Fintech companies. The success achieved in ensuring data safety, improving the NPS score, and enhancing customer satisfaction validates the potential for similar strategies across the Fintech sector.
