What is Email Marketing?

Email marketing is the practice of sending targeted messages to a list of subscribers to nurture relationships, drive sales, and share content. It remains the highest-ROI channel for small businesses because it's owned, measurable, and directly tied to revenue when paired with segmentation and automation.

Definition

Email marketing spans broadcast newsletters, transactional emails, drip campaigns, and behavioral triggers, delivered through platforms like Mailchimp, Klaviyo, or ActiveCampaign.

Key Facts

  • Average email ROI is reported at $36 for every $1 spent (DMA).
  • Deliverability lives or dies by list hygiene and sender reputation.
  • Segmented campaigns can lift revenue by 760% (Campaign Monitor).

Practical Example
