In their own words
PostBridge
PostBridge helps teams print and mail business documents from PDFs or connected workflows while keeping tracking and mailing records together. Its workspace supports letters, postcards, stamps, shipping labels, tracked delivery, verified delivery, and address verification. A team reviews the quote, and a member must approve a job before it prints. Connections include Clio, QuickBooks, Salesforce, HubSpot, Zoho Books, Google Sheets, Airtable, Google Drive, OneDrive, Dropbox, SharePoint, Google Docs, and Canva. Postal automation is available through REST API endpoints, MCP tools, GPT Actions, SDKs, and agent workflows. PostBridge serves the United States, United Kingdom, and France through USPS, Royal Mail, and La Poste. It is available on web, iOS, Android, and inside ChatGPT. The Business/Profile plan costs $39 a month; it includes five licensed Team members, unlimited free viewers, and separately charged postal usage. An eligible workspace receives one 14-day first trial; a qualifying carrier-QR first trial lasts 28 days. Proof documents can be downloaded for seven years, while letter content and uploaded files have shorter retention periods.
