Email marketing is a digital marketing strategy that involves sending targeted and personalized emails to a group of subscribers or customers with the goal of promoting products, services, or building relationships. It is one of the most effective and cost-efficient methods for reaching and engaging with a targeted audience, nurturing leads, and driving conversions. Email marketing campaigns can include a variety of content types, such as newsletters, promotional offers, product announcements, event invitations, and educational content. By segmenting email lists based on demographics, interests, or past behavior, businesses can tailor their messaging to meet the specific needs and preferences of each subscriber, increasing the likelihood of engagement and conversion.
