The Mail app in macOS Catalina has been updated to allow you to easily block and unsubscribe to emails. It can block all email from specified senders and move their messages directly to the trash.
When you block mail from a specific sender, those emails will be automatically moved into the trash. I’ve found this to be a great time-saver in my never-ending battle with phishing and spam.
Just click the sender’s name in any email header and then click Block. Boom! They’re blocked
Apple has built a new unsubscribe button in Mail that will appear above the email header from commercial list senders. Clicking the new link will send a request to have your email address unsubscribed from the list. This means you’ll no longer have to search through an email to find the “unsubscribe” link. Whoo hoo!
macOS Catalina Mail also lets you “mute” an email thread that’s gotten out of hand. This allows you to mute that email thread, which will stop any future incoming notifications from chiming your device.
Click on an email in your inbox. Then go to the Mail menu bar and select Message. You’ll see various options, including “Mute.”
Update: All the features I described in this article worked in at least one beta I used, but the feature in question seems to have disappeared in the final version of Catalina. Apple’s tech support has offered no good solution/answer so far.
