How to Turn off Highlighted Messages in Apple Mail

Adjust Mail's rules to remove highlighting

In Mail, Apple's native email client, you may find that some messages in your inbox are highlighted. In particular, messages coming from Apple are often highlighted in blue. This happens because of preset rules in Mail's Preferences area. If you don't want your messages from Apple or anyone else highlighted, it's easy to turn off any previously set rules, as well as remove existing highlights.

The information in this article applies to Apple Mail 9.3 and later versions.
