Email marketing is a digital marketing strategy that involves sending targeted, personalized, and relevant emails to a group of individuals or a specific audience. The primary objective of email marketing is to build and nurture relationships with current and potential customers, promote products or services, drive engagement, and ultimately achieve specific business goals. It is a cost-effective and powerful way to communicate directly with your audience, deliver valuable content, and encourage action, such as making a purchase or signing up for a webinar.
