Several elements can influence the load speed of an email:
Image size: Large images take longer to load, slowing down the entire email. File formats: Some file formats, like GIFs, can be heavier than others, affecting load speed. External links: Emails that pull data from external servers can experience delays. Code complexity: Complex HTML or CSS can slow down the rendering of an email. Server speed: The server hosting the email content can also impact how quickly it loads.
