Personal Mail International (PMI) vs Stable: overview

Personal Mail International (PMI)

Few virtual mailbox providers can claim uninterrupted operating history since the 1980s; PMI is one of them, founded in Mendham, New Jersey in 1987 by Ruth Sayward after she noticed the gap while working in human resources at a Fortune 500 multinational. Today the company remains woman-owned and woman-run, serving customers across more than 50 countries. Its age shows in how pricing is handled: services are described in prose rather than laid out on a self-serve plans page, so getting an exact monthly figure typically means a phone call or email, a trade-off for the extras (data maintenance, special handling, junk-mail removal) a newer, app-first competitor usually skips.

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.
