HTML Only card option

Would be great to be able to customize the email that accompanies each post rather than have the entire post be sent by email. In my case, I sometimes embed youtube content in my post - however when that arrives by email, clicking on the video sends members to youtube NOT to my site (not ideal). If there were an HTML card customization option I could choose what’s in the email – not only giving me more control over my content, but helping (in my use case) ensure that I can drive people to my website and not a 3rd party website.
