In the past few years, we have covered a whole host of WooCommerce extensions that make your site more customer friendly and increase your sales. WooReminder for WordPress can also help. It sends reminders to your customers to re-order items they have purchased earlier.
The goal of this plugin is to remind your customers to do business with you once they have run out things they purchased from your site in the past. It’s like an Amazon Dash Button with you in charge instead of customers requesting replenishment.
WooReminder allows your customs to reorder by clicking an e-mail link. You simply have to set reminder days for your products, and the plugin does the rest. It also shows you how well you are doing in customer retention. This is a commercial plugin by a CodeCanyon author.
