Scale adds native integrations and team permissions; Custom adds AI routing, extraction, SSO and HIPAA BAAs. Vendor-reported results: 60% less mail handling time and 50% lower mail costs.
Frequently asked questions
What is Stable, and what does it replace?
Stable combines a permanent US business street address with a digital mailroom. Mail arrives at a Stable address, is scanned and uploaded to a dashboard or pushed into your systems. Teams can open and scan, forward, shred or deposit checks, and use AI summaries and routing instead of manual sorting and inter-department forwarding.
How long does it take to switch our business address to Stable?
Sign-up is self-serve and the onboarding questionnaire takes about 10 minutes. Stable then generates pre-filled paperwork and prioritised guidance for updating the state, IRS and vendors, and offers a dedicated person to walk through the process. Mail can be forwarded from your existing address, and a 30-day money-back guarantee applies.
What does Stable cost for a growing team?
Grow is $49/month billed annually ($59 monthly) with one user included and a three-user cap. Scale is $83/month annually ($99 monthly) with unlimited paid users at $30/month each; extra users on Grow cost $20/month. Junk mail does not count against limits, but mail above the plan limit is charged at $3 per piece.
How does Stable handle security and compliance?
Stable states it adheres to SOC 2 Type II, is fully HIPAA-compliant with BAAs available, encrypts mail data in transit and at rest, and applies permission-based access with every action logged for auditing and accountability. The Custom plan adds custom user permissions, SSO (for example Okta or OneLogin) and support for advanced security reviews.
Which tools does Stable integrate with?
The site lists Slack, HubSpot, Microsoft Teams, Google, Dropbox, Asana, Notion and Zapier, plus API and webhook access for building custom workflows. Native integrations and team permissions start on the Scale plan, while configurable AI routing and extraction rules are Custom-plan features.
What happens if we exceed our mail volume?
Grow includes 30 pieces per month (360 per year) and Scale includes 50 per month (600 per year), both subject to the Fair Use Policy. Obvious junk mail is filtered and does not count. Mail above the limit is charged at $3 per piece, and Stable says high-volume discounts can be discussed.
