Email Marketing means sending promotional or informational emails to a list of subscribers. Businesses use it for newsletters, discounts, new product launches, and more.

• Example: An e-commerce site sends a weekly email newsletter with top product recommendations.
• Key point: Customers receive the message in their email inbox, which they open at their convenience.
