Several factors can influence the loading speed of an email:
Image Size: Large images can significantly slow down the loading time. Compressing images can help. Embedded Videos: While engaging, videos can also make emails load slower. Using thumbnails linked to external videos is a better option. Code Complexity: Overly complex HTML and CSS can delay rendering. Simplify your code for better performance. External Links: Emails that fetch data from external servers can be slow. Limit the use of external resources.
