When designing an marketing email, I often recognize that the design for example in Outlook Desktop does not look similiar to the template that I've designed in marketing. However, I've noticed that in Outlook through the web browser or for example Chrome, the design looks good.

The problem that I've encountered is for example that spaces have been added between sections and that element in sections has been moved to the right or left instead of being in the center as it is coded with the toolbox itself.

This is a huge issue for my customers that have a variety of customers using different browsers and email clients.
