Email marketing is one of the foundation points of digital marketing, where companies can directly approach the audience. Personalized well-crafted e-mails can help in molding strong relationships with customers and can promote brand awareness and sales of products or services. Newsletters, special offers, product releases, event announcements are some of the types of campaigns usually sent to targeted groups of the audiences through an endeavor to create maximum response and conversion. Automation tools allow for timely and relevant communications, while performance analytics helps refine strategies to bring about better outcomes. Email marketing can be one of the most expensive marketing channels, with an off-the-chart return on investment, yet it has remained an indispensable tool for building customer loyalty in a competitive landscape increasingly going digital.
