• Automation: Utilizes automated tools to deliver tailored ads and content across multiple platforms to a group of accounts.
• Targeting: Focuses on specific groups of accounts based on predefined criteria like industry, revenue, or company size.
• Scale: Allows marketers to reach a larger number of accounts while maintaining some level of personalization in messaging.
