The key difference from an autoresponder is that workflows are smart: They can change the course of your automated series based on what your prospect will find useful. For instance, if a new subscriber receives a welcome email and the subsequent email is set up to send them an offer that they already found and downloaded on your site, the workflow tool will know and adapt. In an autoresponder, a user receives a specific set of emails at specific time intervals no matter what action they take.

Coupon: Unlike the job application, you probably know very little about someone who has stumbled upon one of your online coupons. But if they find the coupon valuable enough, they may be willing to provide their name and email address in exchange for it. Although it's not a lot of information, it's enough for a business to know that someone has interest in their company. 

Lead Qualification and Filtering is the process of determining whether a lead is ready to be passed on to sales based on things like customer demographics and behaviours. Some leads will be filtered out, because they are not yet at that stage or appear less promising than others – focussing on unqualified leads is a waste of time and resources. Customer relationship management (CRM) software can be used to track and evaluate leads before distributing them to sales.

If you abandon the page, are you retargeted with ads? When you resize the window, does your landing page respond accordingly?
