In dividing your list in this manner, you give yourself the ability to send more targeted communication. Some customers want both product and sales updates, while others might only want to hear about new versions. If you don’t give them the chance to choose, you risk losing them all-together. Since customers make the best buyers, it’s fairly obvious why you want to keep them subscribed to your customer email list.

Attention scarcity is driving a shift from “rented attention” to “owned attention”. Historically, most marketing has been about renting attention other people have built. An example of this would be if you purchased an ad in a magazine or rented a tradeshow booth. But in the noisy, crowded market that today’s buyers live in, rented attention becomes less effective as attention becomes even scarcer. Of course, this is not an either-or proposition; you will ideally use a mix of rented vs. owned attention for your lead generation efforts to be affective.
Remember when we talked about lead scoring? Well, it isn’t exactly doable without your sales team’s input. How will you know what qualifies a lead for sales without knowing if your defined SQLs are successfully sold? Your marketing and sales teams need to be aligned on the definitions and the process of moving a lead from MQL to SQL to opportunity before you even begin to capture leads.
Visitor Tracking: Hotjar has a heatmap tool — a virtual tool which creates a color-coded representation of how a user navigates your site — that helps you understand what users want, care about, and do on your site. It records visitors and tells you where they spend the most time on your site. You can use it to gather information on your lead generation forms, feedback forms and surveys, and more.

This vast quantity of information also means that customers are no longer as interested in listening to a traditional sales pitch that doesn’t relate directly to their needs and it might even push them away. It is now important for companies to focus on generating new leads by developing a strong internet presence. This is often accomplished using inbound marketing methods that employ techniques like search engine optimisation and content marketing.
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%.

How should you balance useful content with solicitations for sales or offers? One of the greatest risks of an auto-responder program is having users become frustrated with hard-sales attempts and subsequently marking your email as spam, opting-out, or simply not opening future emails. All of the aforementioned activities can lower your quality score with email service providers and make it harder for your email sends to get into the inbox. Therefore, it's very important that your auto-responders actually contain useful information. While it's acceptable to include a sales offer along with useful information in each email, it is not advisable for you to make a sales-only email any more frequently than every fifth email in the series in order to protect your email sender reputation.

Don't use CTAs to drive people to your homepage, for instance. Even if your CTA is about your brand or product (and perhaps not an offer like a download), you should still be sending them to a targeted landing page that's relevant to what they are looking for and includes an opt-in form. If you have the opportunity to use a CTA, send them to a page that will convert them into a lead.
Content is a great way to guide users to a landing page. Typically, you create content to provide visitors with useful, free information. You can include CTAs anywhere in your content — inline, bottom-of-post, in the hero, or even on the side panel. The more delighted a visitor is with your content, the more likely they are to click your call-to-action and move onto your landing page.
Companies considering the use of an email marketing program must make sure that their program does not violate spam laws such as the United States' Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN-SPAM),[9] the European Privacy and Electronic Communications Regulations 2003, or their Internet service provider's acceptable use policy.

I am just writing a new email marketing strategy for my website now it’s been re-designed and I have more time to work on my marketing. Having subscribed to numerous blogs, websites, etc. I agree with the poster above, you need to get the number and frequency right. I have often unsubscribed because of the constant barage of emails some organisations send.
The problem is that information abundance equals attention scarcity. This is known as attention economics. Social scientist Herbert Simon was the first person to discuss this concept when he wrote “in an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients.”

Companies that pay attention to each of these steps, especially in the early planning stages, and devote the right resources and budget, tend to perform better than the competition. The process isn't simple, and ignoring any of these steps can lead to poor outcomes. Building a killer process, on the other hand, leads to sustained growth and profitability.
Over time, the popularity of email marketing campaigns resulted in personal email inboxes that were overflowing with the latest and greatest offers. Email campaigns grew and people grew tired of them. Laws that allowed customers to unsubscribe breathed new life into email marketing campaigns as customers could easily pick and choose the companies they were interested in.
