Advertisers may also deliver ads based on a user's suspected geography through geotargeting. A user's IP address communicates some geographic information (at minimum, the user's country or general region). The geographic information from an IP can be supplemented and refined with other proxies or information to narrow the range of possible locations.[28] For example, with mobile devices, advertisers can sometimes use a phone's GPS receiver or the location of nearby mobile towers.[29] Cookies and other persistent data on a user's machine may provide help narrowing a user's location further.[28]
As with offline advertising, industry participants have undertaken numerous efforts to self-regulate and develop industry standards or codes of conduct. Several United States advertising industry organizations jointly published Self-Regulatory Principles for Online Behavioral Advertising based on standards proposed by the FTC in 2009.[109] European ad associations published a similar document in 2011.[110] Primary tenets of both documents include consumer control of data transfer to third parties, data security, and consent for collection of certain health and financial data.[109]:2–4 Neither framework, however, penalizes violators of the codes of conduct.[111]

Now, for a lot of people, this may sound like spam, and while there are some similarities, there are also some important differences. An effective email blast/newsletter will actually attempt to offer value to the reader, whereas spam is essentially junk. Additionally, spam is sent randomly to a mass of email addresses with no particular rhyme or reason behind who they send it to; with a business email blast, the whole idea is to target people that, for one reason or another, are assumed to be interested in the topic. Sticking to the fundamental rules for email blasts can help keep them distinguished them from spam as much as possible.


As mentioned before, the type of email campaign you send depends entirely on your goals with email. If you’re looking to drive direct sales then sending marketing offer and announcement campaigns are going to return the best results, however if you are simply looking to keep your existing customers up-to-date on the latest projects, products or developments at your company, then sending a regular newsletter is going to be the best way to achieve that.

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.
