Use Tables for Layout One of the most recommended practices is to use tables for layout. While this might seem outdated in the context of web development, it remains the best practice for email design due to the inconsistent support for CSS across various email clients.
Limit the Use of CSS To ensure better compatibility, it's advisable to limit the use of CSS, especially external style sheets. Instead, use inline styles to ensure that your email design renders consistently across different platforms.
Optimize Images Optimizing images is another efficient coding practice. Use compressed images to reduce the email's overall size, which can help in faster loading times. Additionally, always include alt text for images to improve accessibility and ensure that your message is conveyed even if the images do not load.
