E-mail design encompasses layout, typography, color scheme, images, branding, and the overall user experience across devices—especially mobile. Good email design not only reflects the sender’s brand identity but also guides the reader’s attention through clear hierarchy, compelling calls to action (CTAs), and accessible formatting. It often involves the use of HTML and CSS to create responsive, visually appealing messages that load correctly across different email clients. Effective email design balances aesthetics with functionality to enhance communication, increase open and click-through rates, and achieve specific marketing or communication goals.
