In the 1990s, the term Digital Marketing was first coined,. With the debut of server/client architecture and the popularity of personal computers, the Customer Relationship Management (CRM) applications became a significant factor in marketing technology. Fierce competition forced vendors to include more service into their software, for example, marketing, sales and service applications. Marketers were also able to own huge online customer data by eCRM software after the Internet was born. Companies could update the data of customer needs and obtain the priorities of their experience. This led to the first clickable banner ad being going live in 1994, which was the "You Will" campaign by AT&T and over the first four months of it going live, 44% of all people who saw it clicked on the ad.
Email marketing - Email marketing in comparison to other forms of digital marketing is considered cheap; it is also a way to rapidly communicate a message such as their value proposition to existing or potential customers. Yet this channel of communication may be perceived by recipients to be bothersome and irritating especially to new or potential customers, therefore the success of email marketing is reliant on the language and visual appeal applied. In terms of visual appeal, there are indications that using graphics/visuals that are relevant to the message which is attempting to be sent, yet less visual graphics to be applied with initial emails are more effective in-turn creating a relatively personal feel to the email. In terms of language, the style is the main factor in determining how captivating the email is. Using casual tone invokes a warmer and gentle and inviting feel to the email in comparison to a formal style. For combinations; it's suggested that to maximize effectiveness; using no graphics/visual alongside casual language. In contrast using no visual appeal and a formal language style is seen as the least effective method. A DAY IN THE LIFE OF A DIGITAL MARKETING MANAGER | WHAT DOES A DIGITAL MARKETER DO? & SALARIES
The "sharing economy" refers to an economic pattern that aims to obtain a resource that is not fully utilized.

One of the limitations of the 4Ps approach is its emphasis of an inside out-view.  An inside-out approach is the traditional planning approach where the organisation identifies its desired goals and objectives, which are often based around what has always been done. Marketing's task then becomes one of "selling" the organization's products and messages to the "outside" or external stakeholders. In contrast, an outside-in approach first seeks to understand the needs and wants of the consumer.
Market segmentation consists of taking the total heterogeneous market for a product and dividing it into several sub-markets or segments, each of which tends to be homogeneous in all significant aspects. The process is conducted for two main purposes: better allocation of a firm's finite resources and to better serve the more diversified tastes of contemporary consumers. A firm only possesses a certain amount of resources. Thus, it must make choices (and appreciate the related costs) in servicing specific groups of consumers. Moreover, with more diversity in the tastes of modern consumers, firms are noting the benefit of servicing a multiplicity of new markets.
Marketing warfare strategies are competitor-centered strategies drawn from analogies with the field of military science. Warfare strategies were popular in the 1980s, but interest in this approach has waned in the new era of relationship marketing. An increased awareness of the distinctions between business and military cultures also raises questions about the extent to which this type of analogy is useful. In spite of its limitations, the typology of marketing warfare strategies is useful for predicting and understanding competitor responses.

In the parlance of digital marketing, advertisers are commonly referred to as sources, while members of the targeted ads are commonly called receivers. Sources frequently target highly specific, well-defined receivers. For example, after extending the late-night hours of many of its locations, McDonald's needed to get the word out. It targeted shift workers and travelers with digital ads because the company knew that these people made up a large segment of its late-night business. McDonald's encouraged them to download a new Restaurant Finder app, targeting them with ads placed at ATMs and gas stations, as well as on websites that it knew its customers frequented at night.

Gap analysis is a type of higher order analysis that seeks to identify the difference between the organisation's current strategy and its desired strategy. This difference is sometimes known as the strategic gap. Mintzberg identifies two types of strategy namely deliberate strategy and inadvertent strategy. The deliberate strategy represents the firm's strategic intent or its desired path while the inadvertent strategy represents the path that the firm may have followed as it adjusted to environmental, competitive and market changes. Other scholars use the terms realized strategy versus intended strategy to refer to the same concepts. This type of analysis indicates whether an organisation has strayed from its desired path during the planning period. The presence of a large gap may indicate the organisation has become stuck in the middle; a recipe for strategic mediocrity and potential failure.
