Marks contacts Do Not Contact for email, with a reason, like the Set Do Not Contact (DNC) batch action.

Mautic MCP tools: https://cotlet.dev/docs/mcp/mautic.md

MCP tool: `mautic_write → set_do_not_contact`

Access: write. Confirm: waits for the user's OK before it runs.

Applies the Set Do Not Contact (DNC) batch action to the contacts you list, with the reason text you give. Mautic then stops emailing them. It reaches nobody, but it changes who receives your campaigns. The list_contacts and get_contact replies show do_not_contact. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `contact_ids` | array | yes | Contact IDs from list_contacts. |
| `reason` | string | no | Reason text stored with the Do Not Contact entry. |
