In my email design I have strange lines appearing under my right hand column. The left hand column seems uneffected. It appears to be the styling from my <a> (the link).
The links don't appear to be linking either.
This is caused by using <a href="#"> or by not using http:// or https://. I replaced all "#" with "http://www.example.com" to resolve.
This was causing my border from my link to show on my column. So if you see other link styling on your column, or a <td> that could be why
