AI-Powered Mail Processing

Postal's core differentiator is its native AI engine that automatically processes inbound mail. It provides instant, accurate summaries of each item, flags urgent communications, and extracts key metadata such as due dates, amounts due, and sender information. The AI can be queried conversationally to pull specific data from documents with citations, effectively turning your postal inbox into a searchable, intelligent database that integrates with your business intelligence tools.

This feature automates a critical business function, ensuring timely responses to government agencies and helping companies stay compliant with evolving corporate and privacy laws.

Electronic Check Deposit & Financial Automation

This feature digitizes accounts receivable. When paper checks arrive at the Postal facility, they are securely scanned, and users can initiate an electronic deposit directly from their dashboard.

Postal FAQ

What is a virtual mailbox and how does Postal's differ?

A virtual mailbox is a service that provides a physical mailing address where your business mail is received, scanned, and made available online. Postal differentiates itself by being AI-native; it doesn't just scan mail, it intelligently processes it. Its AI summarizes content, extracts actionable data like deadlines, flags urgency, and allows for conversational querying, integrating mail management directly into your digital workflow rather than treating it as a separate, manual task.

How does Postal handle security and compliance for sensitive mail?

Postal's entire operation is architected with security as a priority. Its processing facilities are secure and on-site, preventing third-party handling. The platform is built to meet SOC 2 Type II and HIPAA compliance standards, ensuring the secure handling of personal identifiable information (PII) and protected health information (PHI). All data is encrypted in transit and at rest, providing a secure channel for legal, financial, and healthcare correspondence.

Can Postal integrate with my company's existing software stack?

Yes, Postal is designed with integration in mind. While specific API documentation would be sourced from their developer portal, the platform's functionality is built for compatibility. The AI-extracted structured data (due dates, amounts, sender info) can be formatted for export or connected via API to downstream systems like CRMs (Salesforce, HubSpot), ERP software, accounting platforms (QuickBooks, Xero), or task management tools (Asana, Jira), automating workflows from mail receipt to action.

What happens to the physical mail after it is scanned?

Users have full control over the physical mail lifecycle through the digital dashboard. For each item, you can choose to: have it securely shredded and recycled, request it to be forwarded to another address of your choice, or have it stored securely for a defined period. This provides a complete, auditable chain of custody for important documents while allowing for easy disposal of junk mail, all managed remotely.
