If you are still interested in trying direct mail, I would suggest using USPS Every Door Direct Mail Service. With this service, you can target the specific area you are interested in sending a mailer to. If you have the budget, send out 1,000 direct mail pieces to start and see how many sales you get. It’s a good idea to include a promotion, like 15% off of your first purchase, to entice people to buy your product. If you use a code that is unique to your direct mail campaign, you will also be able to track how many sales came directly from your direct mail piece.
It’s a best practice to ask the referrer not only for a friend’s email address, but also for a full name so that the message is personalized. Most important, remember to add the referee’s full name to the email as well. By referencing whom the email content was recommended by, you gain instant credibility and will attain much higher conversion rates.

Email marketing is the act of sending a commercial message, typically to a group of people, using email. In its broadest sense, every email sent to a potential or current customer could be considered email marketing. It usually involves using email to send advertisements, request business, or solicit sales or donations, and is meant to build loyalty, trust, or brand awareness. Marketing emails can be sent to a purchased lead list or a current customer database. The term usually refers to sending email messages with the purpose of enhancing a merchant's relationship with current or previous customers, encouraging customer loyalty and repeat business, acquiring new customers or convincing current customers to purchase something immediately, and sharing third-party ads.
Update your website and continuously offer useful and updated content. Think of your website as a storefront but in the virtual world. In the same way that you do not leave your physical store unattended for a month, you would not do the same to your website. Always update your website and keep it fresh by having a blog, announcing sales, special offers, and new products. Think that you are a customer yourself, so give them the information that they want.
"News Feed Ads", also called "Sponsored Stories", "Boosted Posts", typically exist on social media platforms that offer a steady stream of information updates ("news feed"[38]) in regulated formats (i.e. in similar sized small boxes with a uniform style). Those advertisements are intertwined with non-promoted news that the users are reading through. Those advertisements can be of any content, such as promoting a website, a fan page, an app, or a product.
Newsletters can be sent to the email list you've built from the people who provided the necessary information on your website, for instance, providing these potential customers with news updates about your company, upcoming events and/or special offers – and, of course, reminding them that your business exists and that maybe it's time for another visit.

Even though this falls into just one of the myriad of elements in the 20 portion of the 40/40/20 rule, it is arguably the most important. Nothing will get your piece of direct mail marketing throw into the trash bin more quickly than a glaring typo, a noticeable formatting issue, or an overall poor print quality. If you’re writing the copy, be sure to not only proof it yourself but also have some of your more linguistically-inclined friends and colleagues give it a once over, not only for grammatical and punctuation mistakes but for overall ease of reading and flow. Don’t be afraid to seek as many trusted opinions as possible, and be sure to have thick skin to prepare for any constructive criticisms.
