This one really ruffles our feathers because it implies that you are shoving a bunch of spammy emails down your unsuspecting audiences throats. Blast away! In reality, we want email to be strategic, targeted, personalized, and properly segmented. Additionally, we want the content to be simple, direct, to the point, and useful. With this in mind, the word "blast" seems a bit too intense.


Knowing about your best customers is a key factor in targeted direct marketing. Knowing the customers' basic demographics, such as males 18 to 34 or females with children, is a start. However, a more complete understanding of your customer's profile like their shopping and purchasing behavior in other categories; their attitudes toward trends, products, marketing and media; or their lifestyle habits can help you become even more effective in both your lead selection and the messages you'll use in communicating with the leads.
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?
The call to action doesn’t have to be a sale or discount – it could be advertising a contest or promotion, or incentivizing people to conduct an online survey. Regardless of the nature of the call to action, there must at least BE a call to action. Direct mailing is most certainly not the avenue to send out a blank postcard or flyer that simply informs people of your presence – it’s too expensive, too time consuming, and too hard to efficiently track metrics to garner simple impressions.
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.
