This really nice tip came from the folks over at A New Mac Tip Every Day.
“A feature that has been in the Finder since a long time is the color labels. It is really useful for sorting out files and making folders much more organized. I always wished I could use the same color labels to sort out new emails in Mail. It is possible, but not manually. It must be automated. The way it can be done is with the feature called “Rules”. It can be set up so that Mail will add a color label according to the sender or the recipient’s email address. There are a lots of other possibilities that you can check out and that might work according to your need. What I like best with that is to separate the mail I receive according to the “aliases” that I use. dotMac lets me create aliases of my main email, but everything arrives in the same inbox. The color labels will quickly let me see under which alias I received a specific email. To set up the rule:
- Go to “Mail” and choose “Preferences”.
- Click on the “Rules” tab.
- Click “Add rule”.
- Set the condition according to what you want. I choosed “Any Recipient” and “Contains” and I entered the alias.
- As “Perform the following actions”, choose “Set Color” and “of background” and one of the colors.
This is what it should look like:
