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.
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.

Buying email lists doesn't just damage your deliverability and brand reputation -- it can also put your email account at risk. Email clients like Gmail, Yahoo!, and Outlook don't want to be associated with accounts that recipients repeatedly flag as spam. Email service providers like AWeber go as far as immediately closing your account if it suspects you're sending unwanted content.


Click through rates. Once your subscribers have opened your email, are they actually taking the action you need them to take? If you think that you have a low click through rate, perhaps your body copy is not as effective as it needs to be. Consider the following: Is the copy of your email relevant to the subject line? Did you offer real value to your subscribers in the email? Is your call-to-action clear enough? Is the link easy to find?
Emails triggered by milestones, like anniversaries and birthdays, are fun to get -- who doesn't like to celebrate a special occasion? The beauty of anniversary emails, in particular, is that they don't require subscribers to input any extra data, and they can work for a variety of senders. Plus, the timeframe can be modified based on the business model.
If you’re serious about growing your business, building a healthy email list should be one of your top priorities. When it comes down to it, your list is one of the only online assets that you have 100% control over. Having a solid social media presence is absolutely essential (here’s why), but you’ll always be at the mercy of new and changing algorithms (think Facebook’s Edgerank). And achieving high search engine rankings is great too, but again, you’re at the mercy of changing algorithms and updates. 

To do an email blast, start by finding an email blasting software or website you can use, like MailChimp, Constant Contact, or Vertical Response. Then, upload your email blast and all of the contacts you want to send the email to. When you're writing your email blast, include a compelling subject line, like "Act Today, 25 percent off all shirts," so people are more likely to open it. Also, try to use actionable language throughout your email, like "Buy now" or "Call today," to encourage people to act when they read your email blast.
To build a maling list, marketers collect information about clients and potential customers through in-house research. Many stores offer a substantial percentage off a first purchase when consumers apply for a credit card in the store, or when they opt-in to an email list. Other organizations and companies might set up a booth at a fair or conference, offering a chance to win an iPad when customers sign up for their newsletters and mailings. https://1hdejnvtunmo3ckr2kr3m0y8-wpengine.netdna-ssl.com/wp-content/uploads/2018/01/14-Email-Marketing-Campaign-Ideas-1024x512.png

The DMA’s 2017 Response Rate Report finds that the response rate for mail sent to people on house lists (subscribers who opted in to mail) was 5.1% for the year, and the response rate for prospect lists (potential clients) was 2.9%. These numbers are up from 2003, when house lists drew a response of 4.4% and prospect lists a response of 2.1%. And even though online shopping has surpassed purchases from direct mail pieces, the DMA reports that 100.7 million U.S. adults​ made a purchase from a catalog in 2016, compared with 209.6 million people who made purchases online the same year, per Statista. 

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
When planning a direct mail campaign, don’t forget that you still need to follow the basic direct mail rules. A good list, a good design and a strong call-to-action are a must in order for your direct mail to be a success. Provide information on how people can use the technology you are including and strong content for them to view. If the content is not well designed, then your effort will have been a waste of time.
