Daniel - I have posted on the other thread on this topic.  Details here:   https://feedback.seekingalpha.com/communities/1/topics/84534-seeking-alphas-must-reads-emails-cant-scroll-down-in-apple-mail-on-macbook-pro

In My case latest MacOS and MacMail versions.  The only email I get from ANY source that doesn't scroll is from Seeking Alpha.  "The Week ahead" is the worst - no scroll possible - screen shot on the other thread illustrates NO vertical scroll.  "Must Read" is stubborn, but can be made to scroll.   Honestly, this doesn't instill a lot of confidence in Seeking Alpha.  Been this way for a LONG TIME.

Anyone home???   Okay - I am running Catalina and Mac Mail on a recent iMac - all the latest versions.  The worst email from Seeking Alpha is "The Week Ahead" - see the screen shot below.  Notice no scroll bar on the right???   The only way for me to read this email is to go to gmail.com on Safari where it will scroll.  No emails from ANY other source do this.  I cannot imagine what you guys are doing to make this happen.

No change - The week ahead - same problem today

Well now it's worse . . .  

Wall Street Breakfast: The Week Ahead this email ONLY today shows with no scrolling enabled.  No way to see the whole email.  Again - these Week ahead, Must read, and Wall Street Breakfast are the ONLY emails I get from anywhere that have this problem.  I'm going to try to attach a screen shot from today.  Notice NO vertical scroll bar visible.   

You are not alone - Must-read emails or Wall Street Breakfast are the ONLY emails I receive that will NOT scroll using Mac's mouse 2-finger scroll.  Yes, I can use the scroll slider and I realize this sounds like a nit - but it is annoying.  Requires me to stop reading so I can find the scroll slider.  There is something odd about the tool Seeking alpha uses to generate those emails.
