An email campaign is a marketing strategy that involves sending a series of emails to a targeted group of recipients. The goal is to promote products, services, or events, and to engage with customers. Businesses often use email campaigns to build relationships, share updates, and encourage sales. These campaigns can be personalized based on customer preferences and behaviors, making them more effective. Tools like email marketing software help businesses design, send, and track the performance of their emails. Successful email campaigns typically include compelling content, clear calls to action, and a well-defined audience.
