In Marketing Activities, I do not see a Smartlist tab at the top - nor does it have tiles in the center. Next to the name of my program the Tabs are just : Assets, Set-up, My tokens and Members.
Has the software been re-designed?
You are expecting the Email Send program, which is different than the regular Programs. This has been standard for a very long time.
Please take a look at the docs.marketo.com for more details.
As Takehiro noted, you can create smart campaigns inside the Programs too.
