Google DFP ads in email behaving strangely

I am trying out serving DFP ads in email. I'm following the guidelines here.

I have an ad unit set up just for email
I have a line item targeting that ad unit with just an image creative
The line item doesn't have any targeting restrictions or anything like that

The ad will show up in the email, at least the first time. The strange thing that I'm seeing is, after the first click, clicking on the ad again will often bring me to a blank page rather than the click-through page of the creative. Also, when I reopen the message, occasionally the image will not load. The code in the email looks like this:

<a href="https://pubads.g.doubleclick.net/gampad/jump?iu=/{my_pub_id}/300x250_email&amp;sz=300x250&amp;c={cachebuster}&amp;tile=1">
<img src="https://pubads.g.doubleclick.net/gampad/ad?iu=/{my_pub_id}/300x250_email&amp;sz=300x250&amp;c={cachebuster}&amp;tile=1" />
</a>

We've solved this by turning off cookies in the standard tag using the co= option; adding co=1 to the tag.

<a href="https://pubads.g.doubleclick.net/gampad/jump?co=1&iu=/{my_pub_id}/300x250_email&amp;sz=300x250&amp;c={cachebuster}&amp;tile=1">
<img src="https://pubads.g.doubleclick.net/gampad/ad?co=1&iu=/{my_pub_id}/300x250_email&amp;sz=300x250&amp;c={cachebuster}&amp;tile=1" />
</a>

The only problem (for us) that this creates is that we're unable to serve 3rd party tags, even ones that resolve directly to .gifs, using the standard tag.

Had the same problem and I solved it by using script to redirect click via script on my web server where ad is shown again so that all the cookies can be set.

Link looks like this: http://www.mysite.com/dfpclick.php?adunit=mailing&cbuster=1369608725

Script dfpclick.php:
<?php
/* Google DFP url redirect*/
if ($_REQUEST['adunit']) {
    $sUrl = 'http://pubads.g.doubleclick.net/gampad/jump?iu=/%mygoogleid%/'.$_REQUEST['adunit'].'&sz=1x1&c='.$_REQUEST['cbuster'];
}
?>
<html>
<head>
<meta HTTP-EQUIV="REFRESH" content="0; url=<?=$sUrl?>">
</head>
<body>
<?php
if ($_REQUEST['adunit']) {
    echo '<img src="http://pubads.g.doubleclick.net/gampad/ad?iu=/%mygoogleid%/'.$_REQUEST['adunit'].'&sz=1x1&c='.$_REQUEST['cbuster'].'" width="0" height="0" border="0" style="width:0px; height:0px;" alt=""/>';

}

?>
</body>
</html>

It turns out that DFP for small business requires cookie support to work, even when using the non-JavaScript method of calling ads. So it works fine in web-based clients like Gmail, but it doesn't work in Outlook and the like. DFP Premium can supposedly serve ads in email without requiring cookies.

Using the co= option doesn't work for DFP Small Business. My workaround is:

Use the same code for img <img src="https://pubads.g.doubleclick.net/gampad/ad?iu=/{my_pub_id}/300x250_email&sz=300x250&c={cachebuster}" />

And build a redirect link on your website <a href="http://yourwebsite.com/adunit/300x250_email">. This page reads and filters the response from http://pubads.g.doubleclick.net/gampad/adx?iu=/{my_pub_id}/300x250_email&sz=300x250&c={cachebuster} in order to get the click-tracking link using javascript link=$(xmlDoc).find('a').attr('href'); and redirect.

This workaround doesn't work for rotation (more than one creative/line item is competing for the same ad unit at the same time).

I'd like to know how to serve email ads in rotation using DFP SB
