Autonomous mailing crews for CrewAI

Assign a dedicated agent to manage your physical mail operations. This agent can monitor CRM data and use `send_card` to trigger notes without your involvement. Set up a secondary agent to watch the `list_orders` output. If a delivery fails, the agent can alert a human operator to fix the address in your records.

Role-based mail customization

Give your research agent access to `list_fonts` and `list_cards` to pick the best style for each recipient. This adds a personal touch to every piece of mail sent by the crew. Maintain brand standards by restricting the agent to specific templates found in `list_templates`. This keeps your outreach consistent across different campaigns.

Scale physical outreach with agents

Run high-volume campaigns by letting agents query `list_address_book` for target lists. The crew can process these in batches while staying within your budget. Use `get_credit_balance` as a guardrail tool. If the balance gets low, the agent can pause the campaign and wait for a budget refresh.

        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],

task = Task(
    description="List recent Handwrytten transactions",
