To add a video to the results email, you can use the HTML video tag.

Here's an example for how to add a video:

Make sure to replace "video.mp4" with the URL or file path of the video you want to include. You can also adjust the width and height values to fit your needs.

Note that some email clients may not support video playback, so it's important to include a message in the email that lets the recipient know that there's a video to watch and provides a link to view it in a browser if necessary.

It is important to note that adding a video to the results email using HTML and CSS requires a certain level of proficiency in coding. If you are not experienced in writing code, it is recommended that you seek assistance.

Additionally, when editing the email template, it’s important to be careful not to accidentally delete or write over any existing code, as this may cause issues with the email's formatting or functionality. Always make a backup of your template before making any changes to ensure that you can easily revert back to the original version if needed.
