• Campaign creation and analytics: Retrieve, inspect, and manage email campaigns—enabling your agent to help you monitor, review, or even clean up your marketing activities.
• Mailing list automation: Create or delete mailing lists as needed, so your agent can reorganize or streamline your audience targeting at scale.
• Custom fields and personalization: Build or remove custom fields in your lists, empowering the agent to personalize campaigns and collect richer subscriber data.
• Campaign and list cleanup: Direct your agent to permanently remove campaigns or mailing lists you no longer need, keeping your marketing hub tidy and efficient.
