This direct communication channel allows retailers to engage with customers, promote products, share information about sales or events, and build brand loyalty. Email marketing campaigns often include newsletters, promotional offers, product recommendations, and announcements. By utilizing email marketing, retailers can maintain regular communication with their audience, segment messages based on customer preferences, and track the effectiveness of their campaigns through metrics such as open rates and click-through rates.
