Sorry, I can’t work out what “Images don’t scale” means from those videos. Can you explain?
What I can tell you about images and email HTML is you need to be precise, and in the case if Outlook it’s always best to make the image the actual size needed, opposed to resizing it using settings.
In terms of the colour issue, are we talking about the block that should be yellow but it actually brown? Can you screenshot the settings for that?
Logo not centred is possibly due to the way the image has been added to the project and the email client being used to produce that demo image. So again, need to see settings to help further.
What will really help is if you can share that project?
There is a lot in Email Stacks that doesn’t work consistently across all email clients, sadly, that’s just a reality of HTML for the various clients. Unlike browsers, there is no “standard”. Outlook is a nightmare to work with. For instance it will ingore padding and margin added to images, but will support some margin and padding added to some containers. In Email Stacks, it ignores bottom margin added to buttons but not other elements. And so on.
On top of that there are also various things in Email Stacks that just doesn’t work, at all, but that’s just the nature of the beast, and there is normally a workaround.
I’m not one of the Joe Workman fanboys so don’t/won’t pretend everything he does is perfect. I also don’t buy into his “everything I do is awesome” marketing, but to give him his dues, Email is really very good. I’ve been doing HTML newsletters for 20 years and in that time have tried almost everything. Email is still constantly one of the best I’ve used and miles cheaper that loads.
You just need to understand you are producing HTML that is going to be read in things (email clients) that just don’t/won’t play nice with modern HTML, so you have to get creative.
As web designers we’ve all gotten used to browsers almost perfectly rendering whatever code we throw at them no matter how rubbish our code is. Email clients don’t work like this sadly.
I work in Email Stacks almost daily, so I’ve a better understanding of it’s limitations than many, but that said, there is almost nothing I can’t get it to do, it’s just a case of experimenting.
The only thing I can’t get it to do is to make most email clients support non-web safe fonts, because that can’t be done.

I have a garage full of Joe’s stack, I mean outside garage full collected over the years…and I may just have to park this one there in the next week or two if this project does not work.
