Unfortunately, it is not possible to have more than 1 banner linked to an e-mail zone at any given time.


In a regular web browsing environment, ad servers like the Revive Adserver we host for you use cookies to 'remember' which banner was just displayed. Then, when a click comes a few seconds (or even minutes) later, they can tie that click back to the banner that was displayed initially.


Since e-mail software like Outlook or Gmail does not accept cookies, this is impossible in an e-mail display, and therefore ad servers have to resort to a "one banner at a time" model. That way, when a banner is clicked, they can just look at what banner exactly is linked to the zone, knowing that it must by definition by the one that was displayed previously, and use the landing page URL of that banner for the visitor.


We realize this is unfortunate, but there's nothing we can do about it, since we do not have any control over how e-mail software works.
