Several factors can contribute to slow loading times in emails:
Large Images: High-resolution images can significantly increase loading times. Compressing images before including them in your emails can mitigate this problem. Complex Code: Overly complex or poorly optimized HTML and CSS can slow down the rendering process. Simplifying your code can help speed things up. External Resources: Emails that rely on external resources such as web fonts or hosted images may experience delays due to slow server response times. Heavy Use of Multimedia: Embedding videos or other multimedia elements can also lead to slower load times.
