Use Descriptive Names: Choose descriptive class names that indicate their purpose (e.g., .header, .footer, .button). Keep It Consistent: Use the same class names across different emails to maintain a consistent branding and design. Modular Design: Develop a set of reusable classes that can be applied to various elements, making it easier to create and update email templates. Avoid Conflicts: Ensure that class names do not conflict with each other to prevent unintended styling issues.
