Postal FAQ

What is a virtual mailbox?

A virtual mailbox is a service that provides you with a real, physical street address. When your mail arrives at this address, the service provider (like Postal) securely scans the exterior and, upon your request, the contents of each item. These digital scans are then uploaded to a private online dashboard for you to view, download, forward, or shred. Postal enhances this with AI analysis, instant summaries, and compliance support, turning a basic scanning service into an intelligent mail management command center.

How does Postal handle check deposits?

When a paper check is received in your Postal mailbox, our team securely scans it. You are immediately notified via your dashboard. From there, you can review the scanned check and, with a few clicks, request an electronic deposit. Postal then works with your banking partner to process the deposit electronically through secure methods like lockbox services or remote deposit capture (RDC), accelerating your funds availability without you ever touching the physical check.

What does Postal's AI actually do?

Postal's AI acts as your intelligent mail assistant. It doesn't just scan; it reads and comprehends. For every piece of mail, it generates a concise summary highlighting the sender, purpose, and key action items. It automatically flags urgent correspondence (like legal notices or past-due invoices), extracts critical data such as due dates and dollar amounts, and categorizes mail for you. You can also "chat" with a document, asking questions to pull out specific information, with the AI providing answers and citations directly from the text.

Is Postal secure and compliant for sensitive documents?

Absolutely. Security and compliance are foundational to Postal. Our operations and data handling are built to meet rigorous SOC 2 Type II and HIPAA compliance standards. Your mail is processed in access-controlled, secure facilities. This ensures that sensitive personal information (PII), protected health information (PHI), and confidential business documents are handled with the highest level of security, giving you and your clients peace of mind and helping you meet your own regulatory obligations.
