Digital marketing is defined by the use of numerous digital tactics and channels to connect with customers where they spend much of their time: online. From the website itself to a business's online branding assets -- digital advertising, email marketing, online brochures, and beyond -- there's a spectrum of tactics that fall under the umbrella of "digital marketing."
A common method of assessing a firm's macro-environment is via a PESTLE (Political, Economic, Social, Technological, Legal, Ecological) analysis. Within a PESTLE analysis, a firm would analyze national political issues, culture and climate, key macroeconomic conditions, health and indicators (such as economic growth, inflation, unemployment, etc.), social trends/attitudes, and the nature of technology's impact on its society and the business processes within the society. 
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.
During the 1990s, the resource-based view (also known as the resource-advantage theory) of the firm became the dominant paradigm. It is an inter-disciplinary approach that represents a substantial shift in thinking. It focuses attention on an organisation's internal resources as a means of organising processes and obtaining a competitive advantage. The resource-based view suggests that organisations must develop unique, firm-specific core competencies that will allow them to outperform competitors by doing things differently and in a superior manner.
This refers to how the product gets to the customer; the distribution channels and intermediaries such as wholesalers and retailers who enable customers to access products or services in a convenient manner. This third P has also sometimes been called Place or Placement, referring to the channel by which a product or service is sold (e.g. online vs. retail), which geographic region or industry, to which segment (young adults, families, business people), etc. also referring to how the environment in which the product is sold in can affect sales.  4 Principles of Marketing Strategy | Brian Tracy
The rise of social media platforms has increased the importance of social media marketing, including connecting with customers on social media by persuading them to follow your business, partnering with social media influencers through product placement or paid sponsorships, and paying for advertising on platforms like Facebook or Instagram. The types of advertising that you choose will depend on your budget, type of business, and the preferences of your ideal customers.
The kind of content you create depends on your audience's needs at different stages in the buyer's journey. You should start by creating buyer personas (use these free templates, or try makemypersona.com) to identify what your audience's goals and challenges are in relation to your business. On a basic level, your online content should aim to help them meet these goals, and overcome their challenges.
A fourth question may be added to the list, namely 'How do we know when we got there?' Due to increasing need for accountability, many marketing organisations use a variety of marketing metrics to track strategic performance, allowing for corrective action to be taken as required. On the surface, strategic planning seeks to address three simple questions, however, the research and analysis involved in strategic planning is very sophisticated and requires a great deal of skill and judgement.
Needs: Something necessary for people to live a healthy, stable and safe life. When needs remain unfulfilled, there is a clear adverse outcome: a dysfunction or death. Needs can be objective and physical, such as the need for food, water, and shelter; or subjective and psychological, such as the need to belong to a family or social group and the need for self-esteem.
Personal selling involves an oral presentation given by a salesperson who approaches an individual or a group of potential customers. Personal selling allows for two-way communication and relationship building that can aid both the buyer and the seller in their goals. Personal selling is most commonly seen in business-to-business marketing (e.g.: selling machinery to a factory, selling paper to a print shop), but it can also be found in business-to-consumer marketing (e.g.: selling cars at a dealership). 
Selling: Determine where and how you plan to sell to customers. Consumer product companies, for example, sell to wholesalers who then sell to retailers. In the industrial market, the buying process is longer and involves more decision-makers. You may sell locally, nationally, or even internationally, and some companies only sell their products or services online. Your distribution and sales channels impact who buys your products, when they buy them, and how they buy them.
Connecting the dots between marketing and sales is hugely important -- according to Aberdeen Group, companies with strong sales and marketing alignment achieve a 20% annual growth rate, compared to a 4% decline in revenue for companies with poor alignment. If you can improve your customer's' journey through the buying cycle by using digital technologies, then it's likely to reflect positively on your business's bottom line.
The digital marketer usually focuses on a different key performance indicator (KPI) for each channel so they can properly measure the company's performance across each one. A digital marketer who's in charge of SEO, for example, measures their website's "organic traffic" -- of that traffic coming from website visitors who found a page of the business's website via a Google search. a REALISTIC Day in the Life (Entrepreneur & Digital Marketing Manager)
