In its most basic sense, email marketing is the use of email to promote products or services. But a better email marketing definition is the use of email to develop relationships with potential customers or clients. Email marketing is one segment of internet marketing, which encompasses online marketing via websites, social media, blogs, and more. It is essentially direct mail done electronically instead of through the postal service.
Take the email below from Paperless Post, for example. I love the header of this email: It provides a clear CTA that includes a sense of urgency. Then, the subheader asks a question that forces recipients to think to themselves, "Wait, when is Mother's Day again? Did I buy Mom a card?" Below this copy, the simple grid design is both easy to scan and quite visually appealing. Each card picture is a CTA in and of itself -- click on any one of them, and you'll be taken to a purchase page.
An e-commerce merchant wanting to reach a wider base of Internet users and shoppers may hire an affiliate. An affiliate could be the owner of multiple websites or email marketing lists; the more websites or email lists that an affiliate has, the wider his network. The hired affiliate then communicates and promotes the products offered on the e-commerce platform to his network. The affiliate does this by implementing banner ads, text ads, or links on its multiple owned websites or via email to its clientele. Firms use advertisements in the form of articles, videos, and images to draw an audience’s attention to a service or product.
