I found, in transactional email a template for a review email. It is not clear to me how I can use that template. How can I send automatically an email to a customer with a link to a review about our shop, order or products?
Use Mandrill extension, create a mandrill and mailchimp account, integrate with your magento. Edit your mail templates and you are ready.
An email will be sent by them to your customer pursuing him/her to do a review for your shop/order. Both parties are well known and trusted by consumers so when you work with either Trustpilot or Kiyoh then this will make your customers to trust you even more.
