Internet Marketing Tip: Playing with fonts is fun, and you may be tempted to spice up your emails with exotic fonts. Resist that temptation! Fonts may display differently, or even be replaced by defaults, on someone else's computer. Even if an odd font does display correctly, there is no guarantee that your recipient will appreciate it the same way you do. To avoid any font-based mishaps, stick with fonts that are widespread, easy to read, and understated.
