Send yourself a test email. Before sending an email to a list of people, send one to yourself. Read over the email carefully and keep an eye out for poor formatting or incorrectly sized pictures. Check the email in multiple browsers and use different devices to see if it works across different platforms. Click all the links within the email and make sure they are working as intended.
You have to realize, whether you are a business with a physical presence or work completely online, marketing in the internet is something you have to work with and put to your advantage. This would mean that you could reach millions of people around the world. It is unsurprising, then, that businesses have been moving more and more of their marketing resources online.
Hint: Using the Advanced tab, you can float the image so text can wrap around it. The vertical and horizontal spaces are the amount of space (measured in pixels) you want between the image and anything else on the page. This is usually used to provide space between text in a surrounding article and an image. Copy and paste this: float: left; margin: 0px 10px 0px 10px; into the Style box under Advanced for a quick and easy image float, as you can see here:
The first known large-scale non-commercial spam message was sent on 18 January 1994 by an Andrews University system administrator, by cross-posting a religious message to all USENET newsgroups. In January 1994 Mark Eberra started the first email marketing company for opt in email list under the domain Insideconnect.com. He also started the Direct Email Marketing Association to help stop unwanted email and prevent spam.  
Customers are often researching online and then buying in stores and also browsing in stores and then searching for other options online. Online customer research into products is particularly popular for higher-priced items as well as consumable goods like groceries and makeup. Consumers are increasingly using the Internet to look up product information, compare prices, and search for deals and promotions.
Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016). Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).
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.)
An email blast is a single email message that is sent to a large group of recipients. Email blasts are no longer an email marketing best practice. Email marketers should segment their lists and send targeted messages to their subscribers. All email blasts need to follow the CAN-SPAM Act, include an unsubscribe link, and accurately identify the person or business that is deploying the email.
Email marketing has been around for decades, but it is still one of the most effective digital marketing channels available when it’s done well. Email today needs to feel like one-on-one conversations with each audience member, but it also needs to scale. Make sure your strategies are up-to-date so your emails are getting delivered and cutting through the noise.
