Email Marketing Goals, Strategies, and Challenges

For organizations that do engage in email marketing, a few business objectives, effective strategies, and challenges to hurdle stand out. For instance, increasing leads and improving engagement are the usual goals, personalization and branded content are typical engagement strategies, and limited internal resources are, by and large, the biggest obstacle.

A survey of over 500 marketers in the US reported the following were their main goals for email marketing (The Manifest – The State of Email Marketing in 2018):

  • Retaining customer base (29%)
  • Increasing engagement (22%)
  • Selling products and/or services (17%)
