Purchasing Postbox
Postbox versions 7 and above are sold under an annual licensing model. Your Postbox license is good for one year from the date of purchase.
Yes, we now offer Lifetime Licenses!
Postbox licenses are per user, so one license will cover any/all machine(s) you personally use, Mac or PC. If more than one person will be using Postbox, then additional copies can be purchased at a discount at our Store.
If you purchased Postbox between March 1st, 2016 and September 3rd, 2019, or if you purchased the Lifetime Upgrade option before July 31st, 2010, then you already have a Postbox Lifetime key and no additional purchase is necessary. Download and install the current version of Postbox, and you're good to go.
If you do not have a Lifetime purchase, then a new purchase is required to use the newest version of Postbox.
