Can I add a new contact to a specific brand using the agent?

Yes! Use the `add_contact` action with the Brand ID and contact details. Your agent will register or update the subscriber in BigMailer instantly.

How do I list all the email lists for a particular brand?

Simply ask the agent to `list_contact_lists` and provide the Brand ID. It will retrieve all the mailing lists associated with that brand.

Does the integration allow me to see the statistics of my bulk campaigns?

Yes. Use the `get_bulk_campaign` tool with the Brand ID and Campaign ID to retrieve performance data and metadata for your marketing efforts.
