iPostal1 vs Stable: overview
iPostal1
iPostal1 prices by mail volume rather than a single flat rate: Green at $9.99/mo covers 30 items, Blue at $14.99/mo covers 60, Silver at $24.99/mo covers 120, and Gold at $39.99/mo covers 240, a structure that rewards low-volume customers but can get expensive fast for anyone receiving mail daily. Jeff Milgram, a software engineer, founded the company in 2015 out of Suffern, New York, where it's still headquartered, and grew it into a marketplace of more than 3,000 partner-run locations rather than a single company-operated facility. No domicile, DMV, or residency support exists anywhere in the network.
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.
