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
Project conversion metrics. The general rule of thumb is that the smaller and more targeted your list, the more you can spend per piece. It’s better to make a strong impression to a few than to make a weak impression to many. Know your cost per unit, and project a conversion rate, so you can estimate whether your campaign will have a positive ROI before running it.
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.

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]

If you are able to consult with customers one-on-one, ask any new clients how they heard about you. This will be trickier if you own a restaurant or clothing store since you won’t be able to track down every customer to ask how they heard about you. In these instances, consider asking customers to take a survey on every receipt. Offer an incentive (coupon, discount, etc.) to increase the chances that people will actually fill it out.


There are organizations called blacklists like Spamhaus as well as other filtering organizations like Cloudmark and Brightmail. Email clients like Yahoo and Gmail and Hotmail rely on them to help block spam (yay!). These blacklists leave spam traps or honeypots for shady list sellers to collect. Then, if one of those email addresses ends up in your purchased list, you're in big trouble! It's like having bad credit - it can take a long time and a lot of hard work to rebuild trust with blacklists and until you do, you'll have poor delivery results even if you've stopped using the purchased email list.
People read and subscribe to newsletters because they feel like there is something that they are getting from the content. If you overload an eblast with pitches to sell products and links to affiliate sites, the reader is going to tune out. Inform the reader and get them to your site by engaging them with a topic that relates to the product or service. Check out these golden rules for email blasts for more information on how to keep your readers happy.

Direct mail is a type  of direct marketing in which businesses send letters, postcards or other promotional materials to past, current or potential customers or clients. Direct mail campaigns may be targeted to either a consumer or business or both.  In many cases, the mailing is directed to a target demographic (i.e. home owners) or geographic market (i.e. a specific neighborhood). In most cases, it's mass or bulk mailing, but you can send direct mail in smaller quantities as well.


Email Newsletters are some of the most common and popular forms of email marketing. Use email newsletters to provide your subscribers with timely, expected, and helpful updates from your brand. Include thought leadership or how-tos, announcements about your product or service, insider-peeks into your business, or any other engaging content that adds value to your subscribers’ inboxes.
These metrics give you a high-level overview of how your subscribers are interacting with your campaigns and allow you to compare the success of one campaign to another. If you want to go deeper and see the exact people who opened and clicked your campaign, what links they clicked, etc. you can do so by choosing some of the other reports from the right hand side menu.
Did you know there are organizations dedicated to combating email spam? Thank goodness, right? They set up a little thing called a honeypot, which is a planted email address that, when harvested and emailed, identifies the sender as a spammer. Similarly, things called spam traps can be created to identify spammy activity; they're set up when an email address yields a hard bounce because it's old or no longer valid, but still receives consistent traffic. Fishy, eh?
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.
