PostBridge vs Stannp

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.

Stannp is a direct-mail platform for creating and managing campaigns of postcards, letters and self-mailers. Users upload data, add a design and schedule mail through the platform, which combines automation, personalization and real-time tracking. Customizable engagement reports and campaign insights help users follow activity. Stannp offers integrations with Zapier, REST API, Make.com, HubSpot and Klaviyo; its API can send mail programmatically from an app, website or CRM. The company says campaigns are printed and mailed the next business day. The free plan costs nothing and includes one user, one template, 50,000 contacts and 20 virtual printer items per month, with no minimum or maximum send volume. Starter costs $12 a month and includes one user, 10 templates, 50,000 contacts and 100 virtual printer items monthly.
