I have a pdf that is a call to action is the best way to deliver this with an email?

Assuming you plan on using only Marketo, and no other additional platform (web infrastructure for example) - 

Upload the pdf onto Design Studio -> Images and Files (you might want to create a folder there - "downloads" perhaps). Copy the publicly accessibel URL...

Couple of ways to go about it IMO - 

1) Send an email containing the link to this PDF; you can track who has clicked this link. This is applicable if the PDF is meant for a predefined target audience
2) You would probably have a form (MKTO form I mean) for folks to leave their details - 
        i) Set up the form to redirect to the PDF as soon as filled out
       ii) Set up a triggered smart campaign - once form is filled out send an email with the link to this PDF - this might be useful for two reasons - you want to thank this lead (?) for sharing the info; you want to ensure that the email address entered is valid 

There might be more solutions, but I think this might be simplest?
