Several factors can influence the loading speed of an email:
1. Image Size and Format: Large images or inappropriate formats can slow down loading times. Using optimized images in formats like JPEG or PNG can help. 2. Code Quality: Clean, well-structured HTML and CSS code can improve loading speed. Avoid using unnecessary tags and inline styles. 3. External Links and Tracking Codes: Excessive use of external links and tracking codes can delay email loading. Limit these to essential elements only. 4. Embedded Videos: While videos can enhance engagement, they can also slow down loading times. Use thumbnail images linked to the video instead.
