ROI is probably the most important metric in lead generation. The calculation is fairly simple: it’s the profit or loss you make from investing in a lead, compared against your initial investment. Let’s say you spent $15 capturing each lead, and a lead is worth $20 to you. Your profit from a lead ($5) against your initial investment ($15) gives you an ROI of 33%.
Why does email list segmentation matter? We know that beyond relevancy, list segmentation is important from a revenue perspective. Data from the DMA indicates that segmented and targeted emails generate 58% of all email revenue. On top of this, our research found that marketers who used segmented campaigns noted as much as a 76% increase in revenue–and more than 76% of marketers say basic segmentation is part of their email marketing strategy.
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.
As you can see from the example above, emails following the model contain a succinct headline that highlights the key message of the campaign, as well as supporting information and visuals to help convince readers about the benefits of clicking-through. The reader is then presented with a prominent call to action button that makes it crystal clear what to do next.

When an MQL displays sales-ready behavior, like requesting for a demo or signing up for a free trial, they become a sales qualified lead. These leads are usually handed over by the sales team to an Account Executive (AE). SQLs are close to making a purchasing decision, so the quicker the AE acts, the higher their chances of conversion. A good way to identify an SQL is by applying the BANT framework—do they have the Budget, Authority, Need and Timeframe to buy from you?


When a subscriber is sorted into a segment, it can trigger an automation to send to them. Each person’s interactions with your email campaigns or your website can trigger a sequence of follow-up emails based on their interests, allowing you to hone your message to your targeted audience. For example, if someone visits your pricing page, you know they’re probably further down your sales funnel and will want to follow-up appropriately. Or if they went to a specific product page or clicked on a link for that product, you can send additional information about the product, testimonials and more.
