Project conversion metrics. The general rule of thumb is that the smaller and more targeted your list, the more you can spend per piece. It’s better to make a strong impression to a few than to make a weak impression to many. Know your cost per unit, and project a conversion rate, so you can estimate whether your campaign will have a positive ROI before running it.

Most popular email marketing services offer functionality that strikes a recipient from a list once a certain number of emails to a specific recipient ‘bounced’ back as undeliverable. Don’t be overeager to remove a subscriber, though; there are valid reasons why an email cannot be delivered. Consider only removing such a subscriber after four or five “bounces”.
Besides the fact that email blasts can be spammy and impersonal, they’re also not the most effective way to make money. Although a large-scale email blast is sure to convert, it’s not because sending it was a strategic move — it’s because you cast a wide net. If you crafted a targeted newsletter instead, you’d see a better conversion rate and you’d be able to replicate the strategy many times over. Marissa Petteruti calls email blasts a wasted opportunity to generate more revenue, citing:
However, there is some juice when you buy emails list. If you buy 100,000emails and 85,000 happens to bounce it means you have a conversion rate of 15%. This is quite significant and why should I not buy if 15,000 are going to be good? How long does it take to have 15,000 people subscribe to ones list? If one is able to maintain and convert this 15,000 to become part of a sign up list, then can we not see that buying email lists could be a gold mine?
Your social media strategy is more than just a Facebook profile or Twitter feed. When executed correctly, social media is a powerful customer engagement engine and web traffic driver. It’s easy to get sucked into the hype and create profiles on every single social site. This is the wrong approach. What you should do instead is to focus on a few key channels where your brand is most likely to reach key customers and prospects. This chapter will teach you how to make that judgment call.
Use personalization. Personalizing the content of your emails (depending on your segment from Chapter 3) will make it infinitely more relevant and valuable to them. Personalization is so much more than inserting your subscriber’s first name into the email. You need to tailor the actual content of the email to address their needs. For instance, an online retailer will find it much more valuable to read an email with the subject line, “How to build backlinks to your eCommerce store” than just a generic subject line, “How to build backlinks.”
Does the difference in these terms and their definitions matter? No, of course not, it's semantics! But it is interesting to see how the scope of Internet marketing vs Digital marketing has changed over time. In my books, when discussing alternative definitions, I explain that, no it doesn't really matter, but the scope and responsibility is important to make the most of managing the opportunities. So the scope of digital marketing activities should be agreed within a business and/or between a company and its agencies. The biggest difference is whether digital marketing is simply seen as about communications (online marketing) or whether it is broader, looking at underpinning marketing technology and options for new online business and revenue models.
Market researchers usually have at least a bachelor’s degree in market research, statistics, sociology or other related field. Some researchers, particularly those with companies dedicated to market research and in larger corporations, have a master’s degree. Market researchers who take advantage of internships, either during or immediately after college, will also gain valuable hands-on experience they can use in the future.
