How do I add a new subscriber to a specific segment using the agent?

You can use the 'add_to_segment' tool. Provide the subscriber's email or ID and the specific Segment ID. The agent will immediately associate the contact with that segment in your Flodesk account.

Can I trigger an automated email sequence for a user?

Yes! The 'trigger_workflow' tool allows you to start a subscriber on any of your active Flodesk workflows. Simply provide the Workflow ID and the subscriber's email address.

How do I check if a contact is active or unsubscribed?

Use the 'get_subscriber' tool and provide the contact's email address. The agent will retrieve the profile details, including their current status (e.g., 'active', 'unsubscribed', or 'bounced').
