Basic vs. Pro

DesktopOne runs in two modes: Basic Mode and Pro Mode. In terms of spam filtering, both modes are protected with the same level of security.

For the needs of heavy email users, we offer advanced filtering and configuration options with Pro Mode, which can be activated from within DesktopOne Basic Mode.


Basic Mode is free, and never expires. An annual Pro Mode subscription costs $19.95. FREE

Subscriptions and Licenses

Basic Mode users do not need to worry about subscriptions and licenses: you can download as many copies of DesktopOne as you'd like, and use it on as many computers as you'd like.

In Pro Mode, each subscription automatically includes 2 licenses. This means you can use DesktopOne on two different computers if you'd like. You always have the option to purchase more licenses if you need to use DesktopOne on more than two computers.
