Per the U.S. Bureau of Labor Statistics, a bachelor's degree in marketing, statistics, business administration or a similar field is the common requirement to enter a career in marketing. If you'd like to specialize in e-marketing, you could complete a bachelor's program in this field. Certificate and master's degree programs in e-marketing are also available, if you have a different education background and now want to enter this field.
Once your list is targeted, you need to spend an equally large portion of time coming up with a great deal – even if it means you might lose a bit of money on it. The underlying goal of any marketing campaign is to gain new customers, and it’s worth it to significantly reduce your profit margins to gain said customers. Once you have a surgically-honed list and an amazing offer, then you can spend some time on the design, copy, delivery methods, postage rates, date of delivery, size of the mailer…there are a lot of other options to consider, but following the 40/40/20 rule you can see how important audience and offer truly are.
The fact is, a significant percentage of millennials like mail. It has a built-in emotional response factor. Gallup reported that 36% of people under the age of 30 look forward to checking their mailboxes every day. What’s more, 95% of 18-to-29-year-olds have a positive response to receiving personal cards and letters. Notably this generation will wield a combined $1.4 trillion in spending power by 2020, as reported by Accenture.
Most of the article really talks about how to successfully get an email of a person who has already landed on your landing page/podcast page/affiliate/blog etc. but how to get those people there in the first place is a bigger challenge. Also, one of the ways you can include in your list is by offering free tools/widgets. For example, OpenSiteExplorer by Moz is a great example. Evergreen and very useful for the target audience.
For the design element, odds are that unless you have an artistic background, you’ll be either using a pre-existing template from your printer or having it designed by a graphics designer. The templates from your printer will more than likely have an effective eye flow and a solid ratio of graphics to text – if you go the designer route, be sure to get several mock ups and again seek the opinions of those around you whose opinion you value. And finally, print quality should be self-explanatory – be sure to go with a printer that offers some sort of guarantee on quality, or at the very least one that will offer you a refund or reprint if you’re not 100% satisfied. The last thing you’d want to do is have to settle on a poorly printed mailer to save costs.
The huge advantage of email over social media is that prospects and customers are more likely to see an email than social media. Just posting something doesn't mean that everyone you want to see your message will see it. Your post might not even show up in your targets' social media streams. However, an email will sit in the inbox until it's read (or deleted). 
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.
