Companies considering the use of an email marketing program must make sure that their program does not violate spam laws such as the United States' Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN-SPAM),[9] the European Privacy and Electronic Communications Regulations 2003, or their Internet service provider's acceptable use policy.
Another disadvantage is that even an individual or small group of people can harm image of an established brand. For instance Dopplegnager is a term that is used to disapprove an image about a certain brand that is spread by anti-brand activists, bloggers, and opinion leaders. The word Doppelganger is a combination of two German words Doppel (double) and Ganger (walker), thus it means double walker or as in English it is said alter ego. Generally brand creates images for itself to emotionally appeal to their customers. However some would disagree with this image and make alterations to this image and present in funny or cynical way, hence distorting the brand image, hence creating a Doppelganger image, blog or content (Rindfleisch, 2016). http://www.thebridgecorp.com/wp-content/uploads/emailgraphic.png

Using an omni-channel strategy is becoming increasingly important for enterprises who must adapt to the changing expectations of consumers who want ever-more sophisticated offerings throughout the purchasing journey. Retailers are increasingly focusing on their online presence, including online shops that operate alongside existing store-based outlets. The "endless aisle" within the retail space can lead consumers to purchase products online that fit their needs while retailers do not have to carry the inventory within the physical location of the store. Solely Internet-based retailers are also entering the market; some are establishing corresponding store-based outlets to provide personal services, professional help, and tangible experiences with their products.[24]
Using the word blast says a lot about how you view email marketing. And because so many of us are so very touchy about being characterized as spammers (or just feel bad about “bothering” our subscribers) even using a word that leans toward sounding like spam bothers us. Remember that there are always two definitions of spam. There’s the email marketers’ definition (the CAN-SPAM Act of 2013 definition), and then there’s the consumer definition. The consumer definition of spam is simple and complete: It’s email they don’t want.
"Why aren't millennials moving?" The subject line of this email campaign reads before citing interesting data about relocation trends in the U.S. Trulia doesn't benefit from people who choose not to move, but the company does benefit from having its fingers on the pulse of the industry -- and showing it cares which way the real estate winds are blowing.
In 2002 the European Union (EU) introduced the Directive on Privacy and Electronic Communications. Article 13 of the Directive prohibits the use of personal email addresses for marketing purposes. The Directive establishes the opt-in regime, where unsolicited emails may be sent only with prior agreement of the recipient; this does not apply to business email addresses.
The final part of the description summarises approaches to customer-centric emarketing. It shows how success online requires a planned approach to migrate existing customers to online channels and acquire new customers by selecting the appropriate mix of e-communications and traditional communications. Retention of online customers needs to be based on developing customer insight by researching their characteristics, behaviour, what they value, what keeps them loyal and then delivering tailored, relevant web and e-mail communications.

There are several web-based programs which send out email blasts and which also help the user to remain in conformity to anti-spam laws. The best and most versatile service is Aweber. It charges a flat rate of under $20 per month and everything is unlimited. For smaller email lists, MailChimp is excellent and one can use it for free if there are fewer than 2000 subscribers on the email list, and one only needs to send out a few blasts each month.
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.

A blast email is a type of electronic mailing that is distributed to a large recipient list, and is sent out over a specified amount of time. Often used by marketers, these types of bulk emails were once considered a form of spam, or junk email. Many companies now use blast emails as a legitimate tool to communicate with their customers, and as a result, blast email has become an effective type of email marketing.

Publishers can offer advertisers the ability to reach customizable and narrow market segments for targeted advertising. Online advertising may use geo-targeting to display relevant advertisements to the user's geography. Advertisers can customize each individual ad to a particular user based on the user's previous preferences.[27] Advertisers can also track whether a visitor has already seen a particular ad in order to reduce unwanted repetitious exposures and provide adequate time gaps between exposures.[72]
