Email Double Opt-In Creation?

I need to build a double opt-in and the flow should be:
1 ? outbound invitation edm to opt-in
-user clicks yes
-goes to thank you page or whatever

2 ? system generates a second e-mail to same e-mail address as person who clicked ?yes? (to confirm)
then user reconfirms on this mail by clicking or checking yes.




Has anybody some useful links, resources, scripts?


Thank you!
