AI-powered business address and mail management

Stable is an AI-powered virtual mailbox and business address service for companies that need a permanent street address and a digital way to manage incoming mail. It combines mail scanning, forwarding, shredding, and team-based routing with a browser-based inbox so businesses can work with mail without relying on a physical mailroom.

The product is positioned for startups, small businesses, and larger teams that want to centralize mail handling, reduce manual processing, and keep business correspondence organized. Stable also offers related services such as registered agent support and additional check deposit options, with plan tiers for early-stage teams, growing businesses, and custom enterprise needs.

Core capabilities

Permanent business address

Stable gives businesses a permanent street address they can use with tax entities, government agencies, vendors, and other correspondents.

Digital mail scanning

Incoming mail is scanned and uploaded so users can review it digitally instead of handling everything on paper.

Mail actions and spam filtering

The platform supports scan, ship, and shred actions, plus junk filtering that does not count against plan totals.

Team routing and automation

Mail can be assigned, tagged, and routed to team members or departments, with APIs and webhooks available for automated workflows.

AI-assisted mail processing

AI summaries help users understand what a piece of mail contains without opening the full document, and the pricing page also lists AI data extraction and categorization on higher tiers.

Registered agent service

Stable includes registered agent service, with compliance documents and official mail managed in the platform.

Common use cases

Remote startup mail handling
Startups can use Stable to establish a consistent business address, receive mail digitally, and share mail with founders or advisors while keeping operations remote-friendly.
Shared mail for small teams
Small businesses can centralize incoming mail in one place, route items to the right person, and reduce time spent sorting physical correspondence across a growing team.
Mail-driven operational workflows
Scaling businesses can use automation, API/webhooks, and team workflows to reduce manual handling and move mail-derived information into other systems.
Registered agent and compliance mail
Companies that need compliance support can use Stable’s registered agent service to receive official mail and manage related documents in the same platform.

Businesses with higher mail complexity can use the Custom plan for features such as advanced permissions, SSO, AI routing, and dedicated account management.
