Digital marketing activity is still growing across the world according to the headline global marketing index. A study published in September 2018, found that global outlays on digital marketing tactics are approaching $100 billion.[40] Digital media continues to rapidly grow; while the marketing budgets are expanding, traditional media is declining (World Economics, 2015).[41] Digital media helps brands reach consumers to engage with their product or service in a personalised way. Five areas, which are outlined as current industry practices that are often ineffective are prioritizing clicks, balancing search and display, understanding mobiles, targeting, viewability, brand safety and invalid traffic, and cross-platform measurement (Whiteside, 2016).[42] Why these practices are ineffective and some ways around making these aspects effective are discussed surrounding the following points.

I’d rather not shift into being an email marketing therapist, but I’m not the first email marketer to have issues about being called a spammer. I, too, have been asked what I do in a social situation and had someone respond, “Oh, so you’re a spammer.” Of course, usually people are kidding when they call you a spammer, but but being labeled a spammer is one of an email marketers' biggest fears.
I won’t lie to you, it does take a fair amount of preparation and time to build your authority up to this point. But I guarantee you that if you start implementing the exact same tactics that I’ve listed here, you’ll immediately be able to increase your conversion rate and start building one of the most important resources you’ll need as an entrepreneur.
Have a clear purpose for the blast. Email blasting customers or partners is not an arbitrary task. Each blast should have a concise purpose before you begin to draft it. Determine what you're trying to deliver and how you want the recipients to react to the email. The blast's purpose could be enticing customers to purchase something, updating employees on a new project or initiative, or a newsletter to recap the month's events. Once you determine the purpose of the blast, you can work on making the message more clear to your recipients.[1]
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.
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.
A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online.
It is important for a firm to reach out to consumers and create a two-way communication model, as digital marketing allows consumers to give back feed back to the firm on a community based site or straight directly to the firm via email.[24] Firms should seek this long term communication relationship by using multiple forms of channels and using promotional strategies related to their target consumer as well as word-of mouth marketing.[24]
