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.
To overcome the deficiencies of the 4P model, some authors have suggested extensions or modifications to the original model. Extensions of the four P's are often included in cases such as services marketing where unique characteristics (i.e. intangibility, perishability, heterogeneity and the inseparability of production and consumption) warrant additional consideration factors. Other extensions have been found necessary for retail marketing, industrial marketing, and internet marketing

The product aspects of marketing deal with the specifications of the actual goods or services, and how it relates to the end-user's needs and wants. The product element consists of product design, new product innovation, branding, packaging, labeling. The scope of a product generally includes supporting elements such as warranties, guarantees, and support. Branding, a key aspect of the product management, refers to the various methods of communicating a brand identity for the product, brand, or company. 
After setting the goals marketing strategy or marketing plan should be developed. The marketing strategy plan provides an outline of the specific actions to be taken over time to achieve the objectives. Plans can be extended to cover many years, with sub-plans for each year. Plans usually involve monitoring, to assess progress, and prepare for contingencies if problems arise. Simultaneous such as customer lifetime value models can be used to help marketers conduct "what-if" analyses to forecast what potential scenarios arising from possible actions, and to gauge how specific actions might affect such variables as the revenue-per-customer and the churn rate.
Managers typically establish objectives using the balanced scorecard approach. This means that objectives do not include desired financial outcomes exclusively, but also specify measures of performance for customers (e.g. satisfaction, loyalty, repeat patronage), internal processes (e.g., employee satisfaction, productivity) and innovation and improvement activities.
Some studies indicate that consumer responses to traditional marketing approaches are becoming less predictable for businesses. According to a 2018 study, nearly 90% of online consumers in the United States researched products and brands online before visiting the store or making a purchase. The Global Web Index estimated that in 2018, a little more than 50% of consumers researched products on social media. Businesses often rely on individuals portraying their products in a positive light on social media, and may adapt their marketing strategy to target people with large social media followings in order to generate such comments. In this manner, businesses can use consumers to advertise their products or services, decreasing the cost for the company.
