Can I check the cost of a mailing before I send it?

Yes! Use the `get_mail_job_cost` tool with the job ID. The agent will return the estimated production and postage costs for your mailing.

How do I see if my documents have been printed and mailed?

Use the `get_mail_job_details` tool. Your agent will fetch the current production status (e.g., In Production, Mailed) and provide tracking info if available.

Where do I find my Click2Mail API credentials?

Click2Mail uses your standard account Username and Password for API access. You can find your account details in the Click2Mail portal under Profile.
