As far as we're concerned, your clients never need to know you use Campaign Monitor to send their email campaigns. We never touch your email content, let you add your own confirmation pages and generally avoid mentioning campaignmonitor.com like the plague.
There was however always one thing that bothered us - our generic confirmation pages. If you don't provide your customers with their own landing page for new subscribers, unsubscribers, etc, we provide generic pages as a fallback. Only problem is, these pages were referencing the campaignmonitor.com server.
No more! From today, your generic landing pages will be referenced at your customized sub-domain. For example, your client ABC Widget's unsubscribe confirmation page will now sit at http://abcwidgets..com/
If you guys can think of anything else we can tweak so we don't blow your cover, please let us know.
