If you are using Mailchimp to send an email campaign, you have to be careful not to duplicate the tracking by putting code in your template and then again at the Create Campaign stage.
Always Make "Clean" Templates!
When you create your template, put plain links in or none at all. Untick the little CANDDi tracking box in the bottom right, and make sure it stays unticked!
At the "Create Campaign" stage
Now, and only now, tick the CANDDi tracking box. This will insert the CANDDi tracking code onto all your links :)
If it's still not right when you've sent the next test campaign, give us a call on 0161 414 1080, and we'll have a look too!
