Business email refers to email communication used for official and professional purposes within a business or organization. It typically involves the use of a custom domain (e.g., yourname@yourcompany.com) rather than a generic email provider (e.g., Gmail or Yahoo). Business emails often utilize professional email services and come with features such as custom branding, enhanced security, and collaboration tools. They play a crucial role in professional communication, allowing businesses to maintain a formal and branded online presence while facilitating efficient and secure correspondence among employees, clients, and partners.
