Features That Work for You

Highly optimized e-mail layout

We have A/B tested thousands variations of e-mail surveys so that you don’t have to. Our surveys work great on every device, and achieve the best open and click-through rates.

Customers’ ratings are recorded on the very first click even before they submit the entire survey. Therefore, even if they end up leaving before submitting the form, their rating is captured.

Rolling Net Promoter Score reports

Track how your Net Promoter Score changes over time with our 14-day rolling average chart.

Automatic e-mail throttling checks how often you send surveys to your customers and makes sure they don’t get the survey too often by accident.

Survey scheduling allows you to pick the the best time to send the survey.

Smart follow-up feature magically sends follow-up emails to customers who haven’t opened or clicked your initial survey emails.

This greatly increases your open and click-through rates.

Available in multiple languages

Survey your customers in English, Slovak, German, Italian, Russian, Spanish, French, Czech, Polish, Hungarian, Greek, Hebrew, Croatian, and Portuguese (Portugal).

Application Programming Interface

Our simple RESTful HTTP API allows you to programmatically send or schedule e-mail surveys directly from your code base, as well as export all your ratings and customer data.

A customer profile shows every interaction with an individual customer, allowing you to understand them better when trying to resolve a complex issue.

Close the feedback loop by getting back to your customers. React to their ratings directly from the dashboard.

Customizable Thank You page

Show your customers a customized message right after they submit the survey.

Tailor this message to their rating: ask your promoters to share their good experience or to like you on Facebook.

Segment your customers and understand them better

Facebook Ads integration allows you to push ratings into Facebook and segment your customers using Custom Website Audiences.

Tailor your sequential ads to your promoters, passives and detractors.

Google Adwords integration lets you push your Net Promoter System ratings into Google Analytics and consequently segment your customers in Google Adwords.
