What is Stable?

Notifying a whole team over Slack the moment mail arrives, or triggering a Zapier workflow from a scanned document, isn't something most virtual mailbox providers can do; Stable, launched in San Francisco in 2019, built its product specifically around that kind of team workflow. It's grown into a bootstrapped, roughly $8M-ARR business on the strength of that positioning, with plans running $49/mo (Grow) to $84/mo (Scale), both billed annually, well above what an individual would pay elsewhere in this category for personal mail alone.

Stable works primarily with clients in Remote-first businesses, Startups needing a business address, Teams with distributed mail-handling needs sectors. Its primary differentiator is: Built specifically for team workflows, with Slack and Zapier integrations most mail-only competitors don't offer.
