This window lets you buy SpamSieve. If you’ve already purchased SpamSieve but it’s running in demo mode, you can you enter your name and serial number to personalize your copy of SpamSieve and remove the demo limitations.
SpamSieve has a free trial period that lasts for 30 days or 7 launches, whichever is longer. To use SpamSieve beyond the demo period, you must purchase it. This entitles you to free updates and support.
To purchase, choose Purchase… from the SpamSieve menu. You can use the Purchase Online button to enter the online store.
Soon after paying, you’ll receive an e-mail with your serial number. Enter the name and serial number from the e-mail into the Purchase window and click Personalize. If you need to re-install SpamSieve, you can simply re-enter your name and serial number and click Personalize; there’s no need to purchase again.
If you purchased SpamSieve but cannot find your serial number, click the Look Up My Serial Number button. This will open a form where you can enter your e-mail address and look up your order information.
A license for SpamSieve is good for one person or one computer. You can install it on one Mac, and everyone sharing that Mac can use it (on that Mac). Alternatively, you can install it on your desktop Mac and your laptop; you can then use it on either machine, provided that no one is using it on the other machine.
Note: The Purchase… menu command is not present if you purchased via the Mac App Store. In that case, there is no trial period, and licensing is based on your iTunes account rather than the number of people or computers.
