An email is an electronic message that is sent via the internet and enables information, documents and communication to be sent in digital form.
Some email providers with free services, such as Gmail, WEB.de or GMX, allow adverts to be displayed in the inbox.
An email newsletter, on the other hand, is a regularly sent electronic publication that is aimed at a selected target group and contains current information, news or offers. The purpose of an email newsletter in online marketing is to establish direct communication with subscribers and to continuously address them with relevant content in order to achieve long-term customer loyalty, recurrent purchases or the acquisition of new customers. Data protection requirements such as consent, opt-out options and data security must be realised when sending email newsletters.
