Before you hit send on your next email, check the color of your font. Why it matters...

What color is that email?

You've got a lot of choices in the toolbar at the top and font color can be an important one. If you're asking someone for a favor via email, change the font from black to a softer blue, gray or green. That gives your email a friendlier, more flexible tone. If it's a personal favor, you can choose a friendlier font type. If it's a professional favor, don't get too fancy. If you really mean business, stick to black and stay with a standard Times Roman or Arial font. 

If you're tempted to use red in an email, keep in mind it will come across as aggressive on the other end. Save red for when you're making a very important point and consider it a written alert or alarm.
