Been using SS for awhile and love it. I like the background color vs spamminess and the ability to sort in Apple Mail by color. The one thing that’s very frustrating when going through the junk mail to make sure it didn’t grab something it shouldn’t, is that for some of the colors such as the yellow/gold, It’s almost impossible to see the text over the background color. It would be nice if SS had a text color that was readable for each of the background colors and changed both. Just my suggestion.
SpamSieve used to customize the text color to make it more readable, but unfortunately that’s no longer possible due to changes that Apple made in recent versions of Mail (starting with macOS 14).
