Last October, I went through a period when I thought I was giving up digital art.  As part of that process, I had my e-mail permanently removed from Rendo's mailing list.  I've since returned to my digital art hobby as of last month.

A week ago, as per the FAQ, I e-mailed their marketing department to have my e-mail address removed from their "Do Not E-Mail" list, but have not heard back from them yet.

Is there a more direct way to be put back on their mailing list?
