Email marketing has been around for decades, but it is still one of the most effective digital marketing channels available when it’s done well. Email today needs to feel like one-on-one conversations with each audience member, but it also needs to scale. Make sure your strategies are up-to-date so your emails are getting delivered and cutting through the noise.
Publishers can offer advertisers the ability to reach customizable and narrow market segments for targeted advertising. Online advertising may use geo-targeting to display relevant advertisements to the user's geography. Advertisers can customize each individual ad to a particular user based on the user's previous preferences.[27] Advertisers can also track whether a visitor has already seen a particular ad in order to reduce unwanted repetitious exposures and provide adequate time gaps between exposures.[72]

As advertisers collect data across multiple external websites about a user's online activity, they can create a detailed profile of the user's interests to deliver even more targeted advertising. This aggregation of data is called behavioral targeting.[26] Advertisers can also target their audience by using contextual to deliver display ads related to the content of the web page where the ads appear.[19]:118 Retargeting, behavioral targeting, and contextual advertising all are designed to increase an advertiser's return on investment, or ROI, over untargeted ads.[27]
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers".
There are many vendors out there who sell lists or rent them (though renting means that the list seller maintains ownership and control of the email list). These are collections of email addresses that the vendors sell to any business or individual who can pay the fees. Your email list is considered to be a purchased or shared list if it’s provided to you by a third party, like an email list vendor or affiliate. There's a few ways that vendors build these non opt-in email lists.
Testimonials – If you work with contractors or freelancers, you can reach out to them to offer your testimonials in exchange for a link. Moreover, if you are using consultants’ or specialists’ services, you can also do the same as you do with contractors. Lastly, if there are customers who are happy with your product or service offering and they do not mind you linking to their site, this could be a good opportunity for your business.
If you already have a pretty large database, you also likely have some contacts that have gone quite stale. If so, I recommend running a re-engagement campaign that can help you both scrub your list and prevent the kind of spam and IP issues I addressed earlier, as well as reawaken old contacts that might have forgotten about you, but would actually be great fits for sales.
A call to action (CTA) is a word or phrase that encourages readers and subscribers to do something specific. Examples of calls to action include “subscribe”, “shop now”, “get the free ebook”. You use CTAs on landing pages, blog posts, in email newsletters, and more. When someone does what you want as a result of your call to action, that’s called a conversion. In email marketing, a conversion often means following a link in a newsletter to visit another resource.
Sponsored search (also called sponsored links, search ads, or paid search) allows advertisers to be included in the sponsored results of a search for selected keywords. Search ads are often sold via real-time auctions, where advertisers bid on keywords.[19]:118[53] In addition to setting a maximum price per keyword, bids may include time, language, geographical, and other constraints.[19]:118 Search engines originally sold listings in order of highest bids.[19]:119 Modern search engines rank sponsored listings based on a combination of bid price, expected click-through rate, keyword relevancy and site quality.[21]
Content marketing is more than just blogging. When executed correctly, content including articles, guides (like this one), webinars, and videos can be powerful growth drivers for your business. Focus on building trust and producing amazing quality. And most of all, make sure that you’re capturing the right metrics. Create content to generate ROI. Measure the right results. This chapter will teach you how.
If you create an email blast that asks your contacts to do something (like call you, fill out a form on your website, or take advantage of an offer), make sure you have that high up in the email.  A good rule of  thumb is that your call to action should appear right away, when someone opens your email. If someone has to scroll to find it, it’s in the wrong place. It’s the same philosophy as the old newspaper theory that the stories “above the fold” are those which get the most attention.
Understanding Mobiles: Understanding mobile devices is a significant aspect of digital marketing because smartphones and tablets are now responsible for 64% of the time US consumers are online (Whiteside, 2016).[42] Apps provide a big opportunity as well as challenge for the marketers because firstly the app needs to be downloaded and secondly the person needs to actually use it. This may be difficult as ‘half the time spent on smartphone apps occurs on the individuals single most used app, and almost 85% of their time on the top four rated apps’ (Whiteside, 2016).[42] Mobile advertising can assist in achieving a variety of commercial objectives and it is effective due to taking over the entire screen, and voice or status is likely to be considered highly; although the message must not be seen or thought of as intrusive (Whiteside, 2016).[42] Disadvantages of digital media used on mobile devices also include limited creative capabilities, and reach. Although there are many positive aspects including the users entitlement to select product information, digital media creating a flexible message platform and there is potential for direct selling (Belch & Belch, 2012).[44]
Whether you already have a list of subscribers or are starting from scratch, email marketing services can help. All of the services we cover let you add contacts manually using copy and paste or by uploading CSV or Microsoft Excel files. Some integrate with third-party software enabling you to import Gmail and other webmail contacts, and other customer relationship management (CRM) data, or other software where you might have contacts stored. Depending on the size and location of your list, third-party integration could be key. Verify whether you can export contacts as well (and how easy it is to do so) should you leave the service. Managing users who unsubscribe should also be easy so you're not accidentally contacting anyone who has opted out of your newsletters. 

Many consumers have reservations about online behavioral targeting. By tracking users' online activities, advertisers are able to understand consumers quite well. Advertisers often use technology, such as web bugs and respawning cookies, to maximizing their abilities to track consumers.[60]:60[95] According to a 2011 survey conducted by Harris Interactive, over half of Internet users had a negative impression of online behavioral advertising, and forty percent feared that their personally-identifiable information had been shared with advertisers without their consent.[96][97] Consumers can be especially troubled by advertisers targeting them based on sensitive information, such as financial or health status.[95] Furthermore, some advertisers attach the MAC address of users' devices to their 'demographic profiles' so they can be retargeted (regardless of the accuracy of the profile) even if the user clears their cookies and browsing history.[citation needed]

Establishment of customer exclusivity: A list of customers and customer's details should be kept on a database for follow up and selected customers can be sent selected offers and promotions of deals related to the customer's previous buyer behaviour. This is effective in digital marketing as it allows organisations to build up loyalty over email.[22]
