End user

An end user is an individual who uses a product or service. The term “end user” is generally interchangeable with “customer,” but customers can be retailers buying from wholesalers or third parties. End users are the customers who ultimately use the product.

In the email ecosystem, an end user is the one receiving messages. To reach the right target audience, brands segment their email lists based on data about end users, including behavioral, demographic, and geographic aspects. This segmentation helps them boost engagement, which can further increase open rates, click-through rates, and most importantly, deliverability.
