Best practice in Geographic segmentation
Hey Marketo family,
I was hoping to get some insight from the community as to how you manage your nurture campaigns for multiple geographic segments?
To cater to different time zones I have previously set up campaigns like below. Last year this worked without problem, but not this year sadly with a loss of reporting on opens and clicks (Marketo support are currently investigating).

Is there a better way to manage the nurtures without splitting the campaigns into three? I would like to report on the campaign as a whole if possible.
Please hit me with any tips, advice, critique or personal experiences. I would love to learn how you all work this.
Mitch
