How do we render an EXM Razor view with OOTB Subscribe and Unsubscribe emails?
I'm hoping there is some straight forward setup document on https://doc.sitecore.net/
We have just worked with EXM and used the Sample Newsletter as an example, created the Razor view and used the unsubscribed link that you can find in the One-Column example at this location /sitecore/templates/Branches/System/Email/Messages/One-Column Message
Just be aware that there are two links one is for unsubscribing from the campaign and the other is to unsubscribe from all emails.
Be sure to add the link as a RichText field!
