Review Reminder extension encourages your customers to share their reviews by automatically sending them review reminder emails and auto reward them for a first product review.
Our market and customers tend to move around on a review system for their purchases. Of course who else will not? Reviews help us to think before buying on investing in shopping. Indeed saves our time, effort and money and the same is with our extension that standardizes the review process in a more apt format.
For every single product you purchase, the extension allows you to add a review by getting reminded automatically via an email. This is how you gain trust in purchasing. Admin has the ability to choose to send review reminders through automatic/manual or set the no. of time you send reminders. He has full control to configure the time/date of reminders as per his desire.
The admin can also set a coupon code for its customers which encourages more shopping. Once a customer is done with submitting a review, no reminders would be sent.
