I see there's an integration between Hustle and e-Newsletter, but it seems very light.
I have a couple of questions regarding how to get the two plugins integrated and how they work:
1. The integration option in Hustle settings page is for email list syncing. I guess that means you can capture using Hustle and it'll inject into e-Newsletter's list. Is that all it does?
2. I've configured e-Newsletter for double opt-in, but when I add an email through Hustle it goes into the members list but doesn't trigger the double opt-in option. Is this correct? I'd like to use double opt-in, but Hustle doesn't appear to have it as an option for this itself either.
3. When you're configuring an opt-in with Hustle, and you're not in Test Mode, it requires you to connect to an email service, however e-Newsletter isn't in the list. Is there a guide on how to configure these two plugins together, because it's not perhaps as obvious as I'd hope?
