Hey @wernstrom,

This sort of behavior is really going to be dependent on how the email is designed. For example, reviewing and understanding if the button was a stand-alone block or if it was an image added to a text block, are there additional stylings being applied, etc. would all have various different methods of causing and mitigating this behavior.

From an outside perspective though, I would suggest double checking to see if there were any padding being applied if the button was a stand-alone block. Similarly, if it was an image being pulled into a text block to mimic a button, I would suggest reviewing how the button/image was coded which may be overriding the padding styles applied to the text block. 

There’s a lot to consider when designing your emails! If you were still having troubles with it, I may recommend reaching out to our Support colleagues to see if they can spot the issue or even reaching out to your own email designer to review more thoroughly.
