I've recently built a new email template in Marketo using HTML code I built outside of the program. Upon testing of the email in two nontraditional Outlook displays, a Browser version and a version in my Macbook pro, the email signature line is pushed up into the newsletter. That same email was tested in Gmail and an Outlook version on a Windows machine and no issues were found. Has anyone had this happen before? Below is a screenshot. The code of the email does not provide any obvious cues to explain this.
