Duel is an award winning Customer Advocacy Marketing platform for eCommerce brands and retailers that uses their customers to create emotional connection and enrich the customer experience, boosting conversions and driving high value traffic to sell more online. Using advanced automation and machine learning, Duel engages customers post-purchase and rewards them for creating visual testimonials which are then moderated, curated and put to work at every stage of customer journey.

The Duel extension for Magento enables you to automatically connect your Magento product catalogue, filter which products you want to activate and then display Duel Visual Testimonial Galleries for every single product in your Magento store, without having to aggregate content from social media. By adding social proof to every single product page, Duel increases conversion rates through richer customer experience and keeps shoppers on-site for longer.

In addition, the Duel extension allows you to send automated post-purchase emails to re-engage and reward your customers via Duel product campaigns directly from your Magento store, or integrate with your existing CRM / Marketing Automation platform. By turning your customers into shoppable digital storefronts, Duel drives new customer acquisition with zero media spend.

Account & Pricing

While the extension itself is free, your company must be a Duel client to use the extension. License to the Duel platform is sold on a monthly subscription, with price varying based on the volume of orders processed, advanced functionality and services needed. Get in touch to learn how Duel can work for your brand.
