I haven't seen any mention of the "Send Test Email" trigger. Can anyone give me the scoop on this upcoming feature, what it's used for, and why we should all be amped about the feature.
If you are confused, go to send a test email & see what the new option is.
That feature allows you to test your email scripts in emails.
You can read more about email scripting and find out how to test them in this article: Email Scripting » Marketo Developers
Hope this helps!
