Which type of marketing activity enables upselling and cross-selling?

Remarketing is a powerful marketing strategy that leverages data about previous interactions with customers to promote relevant products and services to them. The key to its effectiveness in enabling upselling and cross-selling lies in its targeted approach. By re-engaging users who have previously shown interest in certain products—whether they visited a website, abandoned a shopping cart, or interacted with an email—remarketing enables marketers to present complementary products (cross-selling) or higher-value alternatives (upselling) that the customer is likely to be interested in.

For example, if a customer views a specific camera on an e-commerce site but doesn't make a purchase, remarketing allows the brand to serve ads for that camera, along with accessories that complement the camera, like lenses or tripods. This strategy not only increases the chances of closing a sale but also elevates the customer's overall experience by making suggestions that align with their interests.

While the other options can play a role in marketing strategies, they do not directly focus on personalizing offers based on previous customer behavior to the same extent as remarketing does, making it the most effective option for facilitating upselling and cross-selling opportunities.
