Button Problem in Campaigns

Button Problem in Campaigns

When creating a button in a Campaign, the button will offset when the email is forwarded.  This has been a problem for quite some time.  We have stopped using the buttons and are using links instead to avoid the button looking funny when the email is forwarded. 

We received an email from Zoho this morning that is exhibiting the same behavior (screenshot attached).  

Could we get a fix please?

Thank you.
