Ruben Bakker, the developer of Mailplane (a very clever app that “brings Gmail to your Desktop”) has responded to customer requests by raising the number of Macs on which you can use the app with a single licence.

In a post on the Mailplane Google Group he explains:

Until recently, a Mailplane single user license was limited to two Macs. Because many users needed Mailplane on more Macs, I’ve decided to lift this limitation:

• Single-user license: *Install on all Macs you personally use.* Use it at home, school, work: just anywhere. *Limitation:* Make sure you’re the only user. Please do not share your license with anyone else.
• Family license: Allow up to five (5) family members *living in the same household* to use Mailplane on their Macs. As with the single user license, there is no machine limitation for any of the five users.
• Site license: For a number of users working at the same organization. Again, each user may use it anywhere.

As a result individuals will pay only USD 24.95 to use it on as many Macs as they own. The family licence costs USD 39.95. For a site licence covering 20 users or more, the price per licence drops to USD 17.95.

Mailplane is not just a slick way into Gmail’s web interface. It adds additional features like “drag and drop” attachments, the ability to integrate multiple Gmail accounts, enabling new mail notifications, sending screenshots and integration with the productivity app OmniFocus through a bespoke plugin.

If you are tempted to be unfaithful to mail.app and start an affair in the Cloud with Gmail (as I am from time to time), Mailplane is a very good investment.

It was good value for money before. Now, for people with more than two macs (like me), it is even better.
