What is Email marketing?

What is Email marketing?

Email marketing is a form of digital communication, specifically digital marketing that allows one to use email to share a company's products or services with existing or potential customers. 

The goal is that every single recipient will become aware of the product. It is hoped that some of them will give their email addresses and become into customers. 

At the same time, a faithful user is more valuable than one dollar. Therefore, email marketing does not usually refer to a transactional email (such as the confirmation of an order or customer service emails), yet be served to strengthen the relationship with customers further as long as any in-touch point is used. 

Therefore, any email a commercial business sends its customers can be considered a marketing email in the most appropriate contextual setting.

The power of email marketing lies in that, like its analog, direct mail, it allows a company to communicate personalized, targeted messaging to individual customers.

Email marketing has remained, along with search engine optimization, an integral part of digital marketing. Although opinions may differ, email marketing is still a potent tool in any digital marketing arsenal.

Pros of email marketing

  • It Requires Little Capital: Email marketing is the cheapest way for companies to reach a broad audience.
  • It's Fast: Email marketing messages can be composed and sent instantly, a critical feature in responsive, 'round-the-clock' marketing.
  • It's Everywhere: According to market research firm Statista, the number of email users has already skyrocketed to 2.55 billion people. This alone is reason enough to cling to this powerful digital channel rather than abandon it.
  • It Comes Back with Data for You to Use: With web analytics, companies can capture extremely detailed data about email marketing activities. This includes everything from open rates, to click-through rates (the number of people who clicked at least once on a link), and other metrics that might steer their strategies.
  • You Can Personalize Your Emails: Unlike direct mail, which cannot be easily personalized for readers or potential new customers.
  • It's Ideal for Distributing Sharable Content: Email is not only quick and easy to send, but if the content is right, you can forward it swiftly too.
  • It's Value-Added Marketing: Consistent emails can gradually raise the brand's visibility even if the customer is not activated.
  • The Permission Model: When you contact an email subscriber, you know that they have permitted you to do so. Email marketing is as much like a club of groupies for marketers as any other form of digital marketing, and very different (and better).

  • You Have to Address Design Difficulties: Modern email marketing demands a memorable brand moment to be delivered meticulously—alongside compatibility on growing numbers of platforms. This means responsive design and a close awareness of what you can send, in terms of content as well as size.
  • It Is an Expensive Mistake: A piecemeal or poorly-targeted email marketing campaign can set your strategy back a long way in particular value loss and time wasted.
