Getting feedback creates an opportunity for businesses to develop themselves in their weak characteristics. Because feedback popups enable customers to send feedback to the company quickly, they are one of the most preferred popup types.
Depending on the business goals, blank areas of the popup may be pointed as required or not. However, users tend to refuse obeying rules of companies, so you need to give freedom to your users for obtaining feedback.
The design of the popup is simple, easily understandable, goal-oriented, and calming due to blue color. Additionally, being nice as saying "Thank you" helps you for winning your customer's heart.
