How do you add opt in form (easily) to Pop UP!?

Hi guys,
This plugin seems to have lots of great features, but I am really surprised that it doesn't have an easy way (that I can see) of adding an email subscriber opt in form.

I didnt even think to check for this, as it seems to be a given now a days.

I would prefer to not have to code one in, are there short codes or something I am missing?

If not can I please have a refund, thanks
