Let’s say that instead of just sending one email to your entire list, you instead separate them into lists based on the type of pizza they buy most often: Plain Cheese, Pepperoni, Everything, Specialty, or something else. Everyone in the “something else” pile can get the generic discount, but send people on the other lists special emails. For example, if you send a coupon for a one-topping pizza to the people who prefer plain cheese or everything pizzas, you won’t make a huge impact. That isn’t what they normally order. But send it to the pepperoni lovers and watch the orders roll in! Customize the discount you’re offering to make it relevant to what people order.
First, try some cold calling. We’ve all gotten those dreaded calls from telemarketers, and while the number of hang-ups sales reps get is enough to make some people quit, this does still work. If it didn’t, people wouldn’t be doing it. The key to success with cold calling is to make sure you have a list of qualified leads. If you’re selling a product for men, for example, make sure your list is primarily male.
When these would-be buyers become interested enough in her products, they request an online demonstration by filling out the form on her landing pages. These requests are routed directly to her salespeople, who, because they’re dealing with warm leads, close roughly 50% of the customers to whom they demo. Molly’s company closes more sales than Norman’s, with fewer salespeople and no time spent on cold calling.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer. 
Of course, if you're going the paid ad route, you could also use Facebook and Google re-targeting to keep that awareness and interest level high. For example, if you've ever noticed after leaving a particular website, that you begin to see their ad everywhere, there's a particular reason for that. Especially if they've already entered your sales funnel, this is a very powerful way to get them to act.

Intent: To get to the intent stage, prospects must demonstrate that they are interested in buying a brand’s product. This can happen in a survey, after a product demo, or when a product is placed in the shopping cart on an ecommerce website. This is an opportunity for marketers to make a strong case for why their product is the best choice for a buyer.
