SpamSieve 3.3.1 is a free update for those who have already purchased the SpamSieve 3.0 upgrade. If you’re using SpamSieve 2 and haven’t upgraded yet, the easiest way is to first let SpamSieve install the new version. At launch, it will show the Purchase window, and you can click the Check Upgrade Options button to get the upgrade discount without having to enter your old serial number.
Normally, SpamSieve will automatically offer to update you to the new version. There are also instructions for updating on this page. SpamSieve 3.3.1 is compatible with macOS 10.13 (High Sierra) through macOS 27 (Golden Gate) and is recommended for all customers using those versions of macOS. Older versions are also available for macOS 10.12 (Sierra) and earlier.
The changes in this version are:
