How to Upgrade
If you purchased Postbox on or after March 1st, 2016 (or a Lifetime License prior to July 31st, 2010), then you already have a Postbox 5 key and no additional purchase is necessary. Download and install Postbox 5, and all of your existing settings and license key will be used. That's it!
If you purchased Postbox before March 1st, 2016, then an upgrade purchase is required to use Postbox 5. For a limited time, previous Postbox customers can upgrade at a discount. Request a discount code through our automated system.
