The Death of Per-Seat Email Pricing
Why paying per inbox in 2026 makes zero economic sense.
For over 20 years, legacy email providers have extracted billions by taxing businesses for every email address they create. Hiring an intern, spinning up an alias, or creating a support handle shouldn't cost you an extra $72 - $200 every year. Discover why forward-thinking companies are leaving per-seat email behind.
Per-seat pricing that multiplies with every hire and alias you add.

Why Modern Teams Switch to Kosh
The Phantom Overhead of Growing Teams
As your team expands from 5 to 50 members, per-seat email costs skyrocket into thousands of dollars annually for simple communication tools.
Punished for Common Business Aliases
Businesses regularly share accounts like billing@, sales@, press@, and hiring@. Traditional providers charge you full seat price for simple routing addresses.
A Predictable Modern Model
Pay for actual platform utility and infrastructure rather than counting heads.
