Platform prefill

Now, accounts with the correct authorizations can seamlessly collect and sign USPS 1583 forms and decrease the total number of steps and time to onboard their end customers. You can learn more about the new API capabilities here.

Does not contain

Workflow automations now support the “does not contain” operator. For example you could now make a rule that assigns all mail to finance that contains “IRS” and does not contain “California”.

Mail operations improvements

This sprint we continued to invest into our mail operations tooling. For example, we released a new tool to help us better visualize all actions taken on a mail item within our processing facility.

Workflow automations

This sprint we began testing workflow automations with a subset of customers. This feature allows you to automatically assign mail to the right teams based on attributes like sender, recipient, mail contents, and more. If you’re interested in learning more, please reach out!

Business recipient updates

You can now see which legal entity is associated with which business recipient in our recipients page!

Mail operations improvements

This sprint we also spent time improving a number of our internal tools to ensure your mail is processed accurately, and quickly. For example, we automated an edge cases associated with failed check deposits to give you more visibility into why a deposit may have failed.

Self-serve mailroom automations

We have shipped self-serve mailroom automations! Previously, this feature was handled by our CX team.

Mailroom automations automate common tasks you may take in your mailroom. Right now, the main task that is supported is team assignment. This new feature allows you to create rules to automatically assign mail to specific teams — for example, mail from the IRS could be assigned to Finance, or mail from the EDD could be assigned to HR.

Combined with permissions, this feature set can ensure that only the right people have access to the right pieces of mail within your organization, automatically.

We hope features like these earn your time back so you can focus on what matters most!

Electronic Check Deposit Onboarding

This sprint we also updated the account verification processes associated with our check deposit product.

Stable now supports Entra SSO! Let us know if you’d like to get it set up 🙂

Routing rules

Customers can now view their active mail routing rules in the setting page of the dashboard. You can use routing rules to conditionally assign mail to your internal teams based on information like who the mail is from, who it is for, where it was sent, and more.

List View (beta)

List view brings an entirely new way of viewing your mail in Stable. It provides a compact, high-density layout that allows users to scan and process mail efficiently with less interaction. By improving information hierarchy and surfacing key details upfront, users can quickly review, prioritize, and take action without unnecessary friction.
