A clean design usually works better than a crowded one. Simple layouts with clear spacing make the message easier to read. Using one or two colors that match your brand can add style without feeling too loud. Adding one image that supports your message can also make the email more interesting, but too many images can slow loading or distract from the text. Short paragraphs with clear sections help the reader move through the content without feeling overwhelmed. Small details like readable font size and enough breathing space can change how the whole email feels. What design style do you think creates a pleasant look without taking attention away from the message?
