Emails often look different because devices have different screen sizes and email apps. Some phones shorten long lines of text, while some computers keep them wide. Certain design elements like images, buttons, or columns may appear in new positions when the screen size changes. Some email apps even block pictures by default, which makes the layout shift. Using a simple design usually reduces these changes. A single column layout, clear text, and smaller images often appear more consistent. Testing your email on different devices before sending can show possible issues. What design approach do you think makes emails easier to read no matter where they are opened?
