What Is Email Marketing?

Email marketing is a digital marketing strategy that involves sending emails to a group of subscribers to promote products, share information, build relationships, and nurture long-term customer loyalty.

Unlike social media platforms — where algorithms control visibility — email marketing allows you to communicate directly with your audience. When someone subscribes to your email list, they are giving you permission to appear in their inbox, which is one of the most personal digital spaces.

Email marketing can be used for:

  • Sharing educational content
  • Promoting products or services
  • Sending newsletters
  • Announcing updates or offers
  • Building trust and authority
  • Driving traffic to websites or blogs
