Automate Letter Dispatch with Briefklick API & n8n

Transform your digital communications into professional printed letters with zero hardware investment. This n8n workflow automates the entire letter dispatch process through Briefklick API integration, enabling you to send real, physical mail directly from your digital systems.

What this workflow does

The workflow receives a webhook POST request containing sender address, recipient address, and HTML content. It processes this data through the Briefklick API to create a professionally formatted document, then automatically sends it to print and mail. The entire process runs hands-free once configured, eliminating the need for physical printers, paper, or manual postal operations.

Perfect use cases

• Invoice delivery: Automatically mail invoices to customers who prefer physical copies
• Official notices: Send legal documents, contract amendments, or compliance notifications
• Marketing mail: Deploy targeted direct mail campaigns triggered by customer behavior
• Customer correspondence: Automate welcome letters, policy updates, or personalized communications
• Document fulfillment: Mail certificates, reports, or statements based on system triggers

Technical implementation

Built using core n8n nodes including webhook trigger, HTTP request for Briefklick API communication, set node for data processing, error trigger for robust handling, and respond to webhook for confirmation. The workflow accepts any trigger type - easily replace the webhook with scheduled triggers, database events, form submissions, or CRM integrations.

Getting started

Requires only a free Briefklick API key from their dashboard registration. The workflow handles all technical aspects of document creation, formatting, and postal dispatch through Briefklick's automated printing and mailing infrastructure. Your HTML content gets professionally formatted and delivered as physical mail without any manual intervention.

Ideal for SaaS operators, automation engineers, and businesses needing reliable document dispatch capabilities integrated into their existing n8n automation workflows.
