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.

While this is obviously more of a guideline than a hard-fast rule, if nothing else it should show you where your efforts need to be placed when undertaking a direct mail marketing campaign. Too often, business owners will spend an inordinate amount of time on coming up with the flashiest, snazziest, most eye-catching design that they are sure will blow everyone away, and then rush to put together the offer and/or the list of folks to send it to. It’s one of the most common mistakes of a mail marketing campaign.
Understand the statistics. Click-through rate or CTR is how often customers click on links contained in your email. There is also a conversion rate, which tracks how many people took action after clicking your link, as well as a rate for how many people opened and read your email. Many email blast software will have these metrics built in. Do not make things in the email blast confusing or complicated as it can prevent people from taking action or even reading the blast.
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".

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:
As opposed to static messaging, chat advertising refers to real time messages dropped to users on certain sites. This is done by the usage of live chat software or tracking applications installed within certain websites with the operating personnel behind the site often dropping adverts on the traffic surfing around the sites. In reality this is a subset of the email advertising but different because of its time window.

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.
E-marketing is a process of planning and executing the conception, distribution, promotion, and pricing of products and services in a computerized, networked environment, such as the Internet and the World Wide Web, to facilitate exchanges and satisfy customer demands. It has two distinct advantages over traditional marketing. E-marketing provides customers with more convenience and more competitive prices, and it enables businesses to reduce operational costs.
To create an effective DMP, a business first needs to review the marketplace and set 'SMART' (Specific, Measurable, Actionable, Relevant and Time-Bound) objectives.[61] They can set SMART objectives by reviewing the current benchmarks and key performance indicators (KPIs) of the company and competitors. It is pertinent that the analytics used for the KPIs be customised to the type, objectives, mission and vision of the company.[62][63]

Alternatively, ad space may be offered for sale in a bidding market using an ad exchange and real-time bidding. This involves many parties interacting automatically in real time. In response to a request from the user's browser, the publisher content server sends the web page content to the user's browser over the Internet. The page does not yet contain ads, but contains links which cause the user's browser to connect to the publisher ad server to request that the spaces left for ads be filled in with ads. Information identifying the user, such as cookies and the page being viewed, is transmitted to the publisher ad server.
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.
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]
