I have a problem concerning the look of my emails, especially the look of a call to action button.
I created a round CTA button that is aligned center:
That's how it looks in Marketo and also in an HTML editor.
When I send the email to my Outlook account, this is also the look I see on a Mac book.
But when I open the email in my Outlook account in Windows, that's how it looks like:
It's not round anymore and aligned left.
Do you have an idea why this is happening and what I could do to change it?
