I have a MailEnable Pro 3 license for sale that was upgrade from a MailEnable Pro 2 license.
MailEnable has been great and I loved using it. I was really happy with it but I've moved to Exchange so I no longer need this license.
Cost on the website is $340 USD, selling for $280 USD or best offer. Please PM me if interested.
