Auto Responder - onclick and open next steps

Hi - I have been scoring internet to see if such an option exists without lot of coding.

I have seen mailchimp, icontact, constantcontact, aweber etc...

I found a basic way to enroll an user into an auto responder campaign and shoot them an email ongoing but that's so old school. My messages are not being targeted - spray and pray

I need to send a pin-point message if someone has opened my first email, a different message if someone has clicked it and a different one for someone who hasn't bothered to even open (no interest at all - send them a coupon with subject line )

I was thinking if someone has a tool (preferably a drag and drop tool but that doesn't matter much) which can do this.

My web app has this need - when someone creates the first step, I want to send them congratulations... and ask him to do step 2. if he hasn't done step 2 after a few days, remind him after few days. Basically, hand-holding him for all steps.

Am I the only guy who see a value for this or are there anyone who sees the value? I have seen a jungle of newsletter providers but nothing advanced on auto responders and transactional.

I have seen marketo (forgive me, $1k/month on this is not I am subscribing) and the likes.

Thanks.
