Return To Sender: Filters, Automations, APIs, and Webhooks

It is now easier to find and manage Return to Sender mail: you can filter for any mail identified by our systems as “Return to Sender”. You can also create mailroom automations and utilize our webhooks +API to automatically send mail marked as “Return to Sender” to the right place.

Data Extraction Improvements

We're continuing to work with a handful of customers on data extraction workflows and we shipped a few improvements as a result

  • Our PDF viewer now highlights extracted data in yellow to enable quick visual verification
  • Request extraction customization directly in the UI

If you're interested in trying out data extraction please contact your Customer Success Manager!

Long-term mail storage (alpha) is now available at all locations

We recently introduced the ability to store mail for longer than our standard 30-day period. We now support this functionality at all of our locations.

Check deposit destination is now available in the API and webhooks

You can now access check deposit destination details directly via the Stable API. The Check object includes a new destinationAccount field showing the account name, last 4 digits of the account number, and deposit type — making it easy to programmatically reconcile deposits across multiple bank accounts without manual lookups or CSV exports. See our API documentation for more details.

Mailroom Automations: Share via Email + Multi-Action Support

We’ve introduced two updates to mailroom automations:

  • Share via Email action. Use this action to automatically email stakeholders a PDF of document scans based on conditions you set
  • Multi-action support. Combine multiple actions together to create workflows tailored your organization

Combined together, you could now support automations like

  • When a check is received, tag it as Accounts Receivable, assign it to the Finance team, and then email your Head of Finance
  • When a document scan contains “1099” assign it to HR and email it your HR team with a custom message
  • When an envelope for “Operations” is received, automatically email that document scan to Zapier or n8n to trigger downstream workflows

Data Extraction Filters

A new filter called "document types" is now available for customers using data extraction. In addition to the new filter, mail item cards will now include the document type just like tags/teams for a helpful at-a-glance view. If you'd access to AI document categorization or AI data extraction please reach out at priority@usestable.com!

Mail Deliverability

We have improved the systems and algorithms we use to get you your mail quickly and accurately. For example, we shipped dashboard prompts to make it more clear when you need to ask your vendors to update your address information, optimized our STE issuing system, and more.

Multi-Entity ECD

You can now enable Electronic Check Deposit (ECD) for every legal entity you manage. Previously, ECD could only be linked to a single legal entity. Now, when setting up a financial account, you can select which legal entity you want to deposit checks for, giving you more flexibility when managing check deposits across your organization.

You can now use routing rules to automatically assign tags to your mail. Previously, routing rules could only assign mail to teams — now you can also apply tags based on your rule criteria, giving you more flexibility to organize and categorize incoming mail. To get started, create or edit a routing rule and select "Add a tag" as your action.

Long-term mail storage (alpha)

We're piloting extended mail storage for select customers who need to retain documents beyond our standard 30-day window. If your business has document retention requirements and you'd like to explore this option, please contact your account manager.
