Iterable's integration with Email on Acid shows you how your email campaigns will render on real devices and email clients—before you send them. There's no setup required for this feature.
Instructions
In Iterable, navigate to Content > Templates.
Find the template you're interested in, and locate its overflow menu (three dots). On this menu, click Preview on device.
You'll see the Client & Device Previews page, where you can view screenshots of your content on various devices and email clients.
WARNING
Iterable doesn't load user profile data before generating device previews, so
previews for templates that require it may not render correctly. In particular,
Handlebars statements that rely on user profile fields may fail and prevent the
generation of a preview. As a workaround, try using the defaultIfEmpty
Handlebars helper.
