Cost per mille, often abbreviated to CPM, means that advertisers pay for every thousand displays of their message to potential customers (mille is the Latin word for thousand). In the online context, ad displays are usually called "impressions." Definitions of an "impression" vary among publishers,[58] and some impressions may not be charged because they don't represent a new exposure to an actual customer. Advertisers can use technologies such as web bugs to verify if an impression is actually delivered.[59][60]:59
Be sure to look at the tech support offered by each of these companies, as we felt many weren't as available as we would have liked. You'll find that some offer 24/7 phone support, live chat, and email help, while others leave you to rely on online documentation and limited live support hours. The best services offer a combination of self-serve help resources—where you can search FAQs and articles to find your own answers—as well as live support via chat or phone when you can't solve an issue yourself. We cover all of these concerns in our reviews, plus you can get an overview in the feature chart above.
Think targeted marketing when determining the demographic selects for your mailing list. Who are your best customers? A direct mailing list performs better when you target your prospects based on the demographics of your current customers. Our online mailing list service allows you to define your mailing list by age, income, gender, length of residence and more. Each list contains different demographic selects.

The most advanced email marketing services offer custom workflows where you can specify triggers based on actions (such as opening an email or making a purchase) or on inaction (such as ignoring emails). With these services, you can also set up a series of emails (such as tutorials) to be sent to segments of users, and you can pause or stop a campaign at any time. You can also move contacts into new segments once they have completed tutorials.
Keep the email short. If you write an email that's too long, there's a chance that recipients will skim over it or stop reading it at a certain point.[7] This could mean that they miss your call to action, or what you're trying to get across. Try to edit out pieces of information that aren't critical to the overall message. Make messages as short and concise as possible. Avoid over-elaboration or background that can clutter your blast.
Send the email. Once you've uploaded the contacts that you want to send the email to, it's time to send the email to the list. Go over the recipients one more time before sending the email and then send it out. Another option that you have is to schedule the blast to go out at a later date and time. This is a great idea if you may have to make last-minute revisions or want to choose a specific time to send it out.

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". 

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]
A/B testing is trying two different techniques that communicate the same message on a small percentage of your list, seeing whether A or B performed the best, then using the better performing option when you email the rest of the list. It sounds complicated, but there are plenty of email marketing solutions out there that take all the math and guesswork out of it. (All you have to do is come up with the option A and option B you want to try.)
Write a compelling subject line. The subject of your email will be the first thing that people will see when viewing it. Because of the immense amount of spam that exists, it's important that you draw the recipient in enough so that they open the message. The subject line should invite the reader to some benefit or include a sense of urgency which requires action. Avoid cliche marketing terminology like "act now" or "free limited offer" as these subject lines can make recipients feel suspicious and turned off. Your subject line should be 50 characters or less.[2]
Use it to send new subscribers a “welcome” sequence. This is the message that you send to people right after they subscribe to your email list. It could contain a link to your lead magnet for an easy download, a thank you for subscribing, and maybe a call-to-action to check out your most popular blog posts. Every email list needs a welcome series: don’t miss this chance to “woo” your new subscribers and turn them into loyal fans!
Video: Video mailers have a built-in audiovisual player. The video plays after opening the mailer or by pushing a button. With a built-in video screen, people are inclined to instantly watch it. You don’t have to worry about applications or other software; you know that once opened, people will watch it. Since this form of direct mail is relatively new, they can be costly and not affordable for all campaigns. But the costs are starting to come down, so keep an eye on them until you can afford to try them.

Presentation is everything, or so they say. With this old adage in mind, we’ve compiled our best tips for anyone who wants to send emails that subscribers click into a handy email design guide. We cover each facet of design: content, templates, identity, color, images, layout, fonts, and calls to action. Design is as much science as it is art, and we take the guesswork out of what can seem like the most challenging part of sending good emails. 

Because users have different operating systems, web browsers[84] and computer hardware (including mobile devices and different screen sizes), online ads may appear to users differently from how the advertiser intended, or the ads may not display properly at all. A 2012 comScore study revealed that, on average, 31% of ads were not "in-view" when rendered, meaning they never had an opportunity to be seen.[85] Rich media ads create even greater compatibility problems, as some developers may use competing (and exclusive) software to render the ads (see e.g. Comparison of HTML 5 and Flash).
I think what Brian and the testers are missing is that 15k is neither big enough to be impressive nor small enough to be inviting. It’s not a number that works effectively as social proof, and while I can’t test it out myself, I believe, based on evidence for social proof around the web, that DIYthemes would have had much better success with a combined number in the 50k+ range as mentioned above.
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]
