SpamSieve Technical Support

  1. SpamSieve 3.0.4 (released May 17) is compatible with macOS 10.13 through macOS 14 and Apple Silicon Macs.
  2. Apple Mail in macOS 14 Sonoma removes support for Mail plug-ins, so SpamSieve 2 will stop working. SpamSieve 3 has been released with support for Sonoma. Here’s a guide explaining the transition.
  3. If you want to use a pre-release version of macOS or update to the latest release version as soon as it’s ready, check out the SpamSieve public beta.

  1. SpamSieve 3 is a paid upgrade. At the top of the Purchase window, there should be a Check Upgrade Options button that will let you get the upgrade discount—you do not need to re-enter your SpamSieve 2 serial. If you aren’t ready to upgrade your license yet, SpamSieve 3 will run for free for 30 days, and SpamSieve 2 is still available.
  2. The SpamSieve manual includes the list of supported mail programs and OS versions, setup instructions for the different mail programs, a section on iPhone spam filtering, and a FAQ.
  3. When troubleshooting, first take a look at SpamSieve’s Log window, which shows lots of information about what SpamSieve is doing and includes links to relevant help pages.
