Peerfly / CPA Questions

OK, total noob issue, but here goes:

I just got accepted into Peerfly (yay me!), and am in the process of setting up my sites for email/zip offers. What I'm confused about is do I get paid if the visitor only enters their email on the first page, but then does not follow through on the rest of the survey?

I swear this was not done to manipulate anything, but my neighbor saw a promo flyer I created with some of the offers and was genuinely interested in applying for the offers ($1,000 gift card; year supply of chocolate), so she went to my link from her iPhone (on wireless network, not wifi). She entered her email on the first page, as required. Next page was for other personal details like address, DOB and cell and home numbers. At this point she didn't want to give her phone number so she just closed the window and did not continue -- so I would assume this means I do not get credit for the lead? Even though she entered a valid email, but not her personal info? (And I'm not being petty here over $1.30, I'm just really trying to understand this).

She tried the second offer, and this one gave her an error message after she entered her email that it was "not compatible on a Mac." (?!?!?!) Wow, doesn't that really affect a fair percentage of the population, especially those using iPhones? I was planning to create flyers with QR codes directing to the offer, but that seems like a waste of time now if there is this compatibility issue.

I know some other offers also have a survey attached -- does this also need to be completed to receive credit? There must be a large number of abandoned surveys once some visitors see how much more is involved than just an email address.

I checked my Peerfly account and there is nothing showing as a conversion, so I assume the answer is that they do need more than just an email?
