An email list is a collection of email addresses used to send messages to multiple recipients at once. Businesses and organizations often create these lists to communicate with their audience, share updates, or promote products and services. Subscribers usually opt-in to receive emails, ensuring that the list consists of interested individuals. Managing an email list involves collecting, organizing, and maintaining the addresses. Tools like email marketing software help automate the process, allowing users to segment their lists for targeted campaigns. Regularly cleaning the list by removing inactive subscribers can improve engagement and ensure that messages reach the right people.
