Introducing Kintsugi Mail

Imagine having a dedicated digital mailbox just for your sales tax documents. That’s essentially what Kintsugi Mail is! It’s a virtual mailbox service that helps you manage all your important tax-related letters, notices, and messages in one centralized place.

We partner with a service called “Stable” to provide a mailing address just for your tax-related mail. Then, our own AI-powered system takes over to handle everything efficiently and securely.
​
✅ No extra fees! Kintsugi Mail is included in every paid plan at no additional cost.

Kintsugi Mail becomes available once you upgrade from the free plan to any of our paid plan. It gives you instant access to a streamlined system for receiving, reviewing, and responding to official tax mail—all without any extra charges.

Once setup is complete, Stable provides you with a dedicated virtual mailing address. This is where tax agencies and departments will send physical notices, letters, and other official tax documents.

When mail is received at this address, Stable scans each of them and sends PDF version securely to Kintsugi Mail via API.

Kintsugi Mail then automatically forwards those scanned PDFs to your Virtual Mail Group, which works like a Google Group Inbox, housing a list of email addresses as recipients of the tax correspondence.

A unique Virtual Mail Group ID is created for your account. The Virtual Mail Group acts as a distributing list, ensuring that everyone who needs access—your team, your accountant, or even just yourself—gets copies of the incoming tax notices.

To help prevent missed deadlines and ensure timely responses, we recommend adding your own email and a few key Kintsugi team email addresses to the Virtual Mail Group. This allows both you and our support team to track and respond to tax mail promptly.
