The use of software tools and systems to automatically send and manage email communications based on predefined rules, triggers, or schedules. Email automation allows businesses and individuals to create and send personalized messages, follow-up sequences, and targeted campaigns without manual intervention. This process involves setting up automated workflows that respond to specific actions or events, such as a new subscriber joining a mailing list, a customer making a purchase, or a user abandoning a shopping cart. Email automation can include sending welcome emails, promotional offers, reminders, and follow-up messages. By leveraging email automation, organizations can efficiently nurture leads, engage with customers, and streamline communication processes, ultimately improving efficiency and effectiveness in email marketing efforts.
