Simply put, email marketing refers to the use of email communications in a marketing strategy to reach specific business goals. Emails can be used to generate sales, enhance customer engagement (i.e., newsletters), acquire customers, create brand awareness and reward customer loyalty. For existing clients and customers, email marketing emphasizes communication and awareness. For potential customers, emails can be used to entice and attract in an outreach campaign. The most effective email marketing campaign is planned by modality, audience, and goals. Campaigns to onboard new customers, reengage inactive customers, or drive customers from lead to conversion all have unique goals and approaches.
