Great article, but I’d like to play the devil’s advocate for a moment. Personally, I receive emails every day, once or twice or week, or even on the weekends from professionals who are trying to sell me something or giving me a free teleseminar or webinar. I may open the emails or hit delete/spam. Do you constantly want to bombard people with emails when they’re probably received more than they want? What’s considered overkill?

Users with access to the Internet can use many digital mediums, such as Facebook, YouTube, Forums, and Email etc. Through Digital communications it creates a multi-communication channel where information can be quickly shared around the world by anyone without any regard to who they are.[30] Social segregation plays no part through social mediums due to lack of face to face communication and information being wide spread instead to a selective audience.

Companies often use email marketing to re-engage past customers, but a “Where’d You Go? Want To Buy This?” message can come across as aggressive, and you want to be careful with your wording to cultivate a long-term email subscriber. This is why JetBlue’s one year re-engagement email works so well -- it uses humor to convey a sense of friendliness and fun, while simultaneously reminding an old email subscriber they might want to check out some of JetBlue’s new flight deals.

I took-away the point of the article being that content of your emails are the most important component. Looking at a single email or an acquisition blast, I could buy the argument that Subject Lines and From Address determine if the email gets read. But as most of us know, email marketing is more effective at continuing the conversation and building a relationship with our customers.
Email marketing - Email marketing in comparison to other forms of digital marketing is considered cheap; it is also a way to rapidly communicate a message such as their value proposition to existing or potential customers. Yet this channel of communication may be perceived by recipients to be bothersome and irritating especially to new or potential customers, therefore the success of email marketing is reliant on the language and visual appeal applied. In terms of visual appeal, there are indications that using graphics/visuals that are relevant to the message which is attempting to be sent, yet less visual graphics to be applied with initial emails are more effective in-turn creating a relatively personal feel to the email. In terms of language, the style is the main factor in determining how captivating the email is. Using casual tone invokes a warmer and gentle and inviting feel to the email in comparison to a formal style.

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.[26]
Finally, it’s critical you spend time and resources on your business’s website design. When these aforementioned customers find your website, they’ll likely feel deterred from trusting your brand and purchasing your product if they find your site confusing or unhelpful.

It’s interesting you mention Budweiser and branding. Many direct response marketers tend to be dismissive of brand building and may scoff at the idea of using emails and stories to, at least in part, build a brand for their business. What do you say to those people who are more inclined to just put an offer out there in an email and try to make as many sales as quickly as possible?
