Here are some best practices for writing clean code in email marketing:
Use Tables for Layout: While modern web development has moved away from table-based layouts, they are still the most reliable way to ensure consistent rendering across different email clients. Inline CSS: Many email clients strip out external CSS files, so it's best to use inline styles to ensure your designs render as intended. Avoid JavaScript: Most email clients do not support JavaScript, so it's best to avoid using it altogether. Keep it Simple: Avoid complex structures and excessive use of images. Simple and straightforward designs are more likely to render correctly. Test Thoroughly: Use tools like Litmus or Email on Acid to test your emails across different clients and devices before sending them out.
