Grow Your Email List with A Targeted Audience Another digital strategy in digital marketing is building the email list of the targeted audience. It is one of the most effective ways to connect with potential and current customers. A digital agency can help you create a targeted list through social media marketing, SEO, Ads, or even videos. The term “email marketing” refers to the practice of delivering commercial content via email. In a broad sense, every email sent to a potential or existing customer can be considered email marketing. However, the term is usually used to refer to a more specific type of marketing: sending emails with the intention of promoting a product or service.
