When I click on the 'view as web page' link while previewing an email, I get this error message:
Cannot get email content- Customer does not belong to any POD
I was wondering why this is and what I can do to fix it?
Looks like you may need to reach out to Support. Others have asked the same question: https://nation.marketo.com/message/125905#comment-125905
View as Web Page doesn't work in Preview.
(Nor does it really make sense in Preview, since you are viewing the unrestricted web version of the email.)
