I'll answer your questions here and then think about how to answer them on the site. Q: how does information get from my app into yours A: async javascript snippet. my co-founder has the scars to prove it is robust. Q: can I embed per-user links A: yep. our docs are a lot more elaborate than our user interface at this point, but you can do almost anything you desire. best to shoot me an email and i'll explain. peter@userfox.com Q: how do opt-out notifications get back from your app to mine A: we have a simple unsub API to communicate who has unsub'd, we handle the entire unsub from userfox emails obviously. you're going to eventually (soon) send all emails via userfox though. Thanks for the note on the ui issue. we'll get it fixed.
