Remintrex is an email retargeting solution that allows companies to send targeted emails to past website visitors. It works by tracking users' online behaviors as they browse a company's website and visit different pages. Then, Remintrex can send retargeting emails related to the users' interests from their website visit. The solution has maximum reach in 30 countries through partnerships with large email databases. It provides features like personalized content and ability to send offers related to users' website visits. Companies see improved results like higher email open and click rates compared to non-retargeted emails. Implementation involves adding Remintrex tracking code to trigger emails based on user behaviors like homepage visits or adding items to cart.
