Several elements require attention when optimizing your email marketing code:
HTML Structure: Use a clean, simple HTML structure. Avoid unnecessary nested tables and ensure your code is well-organized. CSS: Opt for inline CSS to ensure better compatibility. Avoid external stylesheets as they are often stripped by email clients. Images: Compress images to reduce load times. Use alt text for better accessibility. Fonts: Stick to web-safe fonts to ensure consistent rendering across different email clients.
