Subscription update email for my blog does not include the thumbnail video, or videos, if they exist

When I include Vimeo videos in a blog update, the subsequent subscription update email just has a blank space where the video is on the blog.

The blog showing the video.

The same part of the subscription update email.

Any photos I include are displayed in the email.



At present the email updates don’t format a number of post elements such as embedded videos like in your case and MathJax expressions.
