This was inlined via CampaignMonitor's inline tool -- http://inliner.cm/ -- which normally works great. I think the issue was this line of code:

background-color:#fb8a06;background-image:none;background-repeat:repeat;background-position:4c06);background-attachment:scroll;

Normally, replace this with my original (non-inlined code) of:

background:#fb8a06;background:-webkit-gradient(linear,0 0,0 bottom,from(#fb8a06),to(#fb4c06));background:-webkit-linear-gradient(#fb8a06,#fb4c06);background:-moz-linear-gradient(#fb8a06,#fb4c06);background:-ms-linear-gradient(#fb8a06,#fb4c06);background:-o-linear-gradient(#fb8a06,#fb4c06);background:linear-gradient(#fb8a06,#fb4c06);

When I tested the email with the latter, it worked fine. When I updated the email and forgot to redo this bit, the email was sent live and this is where the issue occurred.

No huge deal, just curious.
