Do email previews in MS Outlook count as "Opens" in Marketo?

[Ken_Ungaro]

As the title suggests, I'm trying to find the definitive answer for this situation.

If a recipient "previews" either my HTML or the TEXT ONLY version of my email in their Outlook Preview Pane, does Marketo count it as an "Open"?

Ken, Email will be treated as Open if pixel downloaded in emails. Like if you have image and if they are automatically downloaded, the it will be treated as open email. With this fundamental, even if email is in preview mode but images got downloaded, yes email is opened.
