The final part of the description summarises approaches to customer-centric emarketing. It shows how success online requires a planned approach to migrate existing customers to online channels and acquire new customers by selecting the appropriate mix of e-communications and traditional communications. Retention of online customers needs to be based on developing customer insight by researching their characteristics, behaviour, what they value, what keeps them loyal and then delivering tailored, relevant web and e-mail communications.
The effort you put into building your email list is one of the best investments you can make online. Having access to the inboxes of targeted prospects means you can continue to build and nurture relationships over time, and become a trusted source of valuable industry knowledge. Then, when it’s time for your prospects to buy, you’ll be the first one who comes to mind.
If all Michael had was the 57k Facebook fans listed right below, I’m not nearly impressed. Combined with the big number above, however, the FB fan numbers serve as crucial verification. If your website has 1,500 FB likes, there is NO WAY I believe you have 500k viewers. But with Michael’s Facebook numbers, I start to believe in that much bigger number above, and it means I probably can’t afford to miss what he’s saying.

Alas, ESPs on shared IP addresses that don't require customers to use opt-in email lists typically suffer poor deliverability. Why? One customer's ill-gotten email address list can poison the deliverability of the other customers on that shared IP address. You're going to want to hitch your wagon to the light side of the email marketing force if you want your emails to actually get into inboxes.
Well, charity: water took an alternate route. Once someone donates to a charity: water project, her money takes a long journey. Most charities don't tell you about that journey at all -- charity: water uses automated emails to show donors how their money is making an impact over time. With the project timeline and accompanying table, you don't even really need to read the email -- you know immediately where you are in the whole process so you can move onto other things in your inbox.
It also emphasises how digital marketing does not occur in isolation, but is most effective when it is integrated with other communications channels such as phone, direct mail or face-to-face. As we have said, the role of the Internet in supporting multi-channel marketing is another recurring theme in this book and chapters 5 and 6 in particular explain its role in supporting different customer communications channels and distribution channels.
A strategy that is linked into the effectiveness of digital marketing is content marketing.[39] Content marketing can be briefly described as "delivering the content that your audience is seeking in the places that they are searching for it".[39] It is found that content marketing is highly present in digital marketing and becomes highly successful when content marketing is involved. This is due to content marketing making your brand more relevant to the target consumers, as well as more visible to the target consumer.
Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016).[42] Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).[42]
It is increasingly advantageous for companies to use social media platforms to connect with their customers and create these dialogues and discussions. The potential reach of social media is indicated by the fact that in 2015, each month the Facebook app had more than 126 million average unique users and YouTube had over 97 million average unique users.[27]
Particular groups of customers can be targeted or even individuals. Offering individual customers special deals on merchandise and/or services on the customer's birthday, for instance, is one example of email marketing personalization. (A restaurant might send an email to customers on their birthday offering 50% off an entree,) Email marketing helps a business develop and maintain a relationship with a customer over time that hopefully results in increased sales and increased customer loyalty.
