## 1. Supported Variables

| Variable | Description |
|----------|-------------|
| `{{lead.name}}` | Full name of the prospect |
| `{{lead.first_name}}` | Prospect's first name |
| `{{lead.company}}` | Prospect's organization |
| `{{lead.service}}` | Requested product or enquiry topic |
| `{{lead.message}}` | Inbound enquiry text |

## 2. Safety Rules

- Variables are rendered safely without executing raw code or exposing cross-workspace data.
- Missing variables default gracefully without breaking the message payload.
- Email header injection protection prevents CRLF characters in subject lines.
