There are several categories of typefaces, but the most commonly used in email marketing include:
Serif - These typefaces have small lines or strokes regularly attached to the end of a larger stroke in a letter or symbol. They are often considered formal and traditional. Sans-serif - These typefaces do not have the small projecting features called "serifs." They are generally cleaner and more modern. Monospace - Each character in these typefaces occupies the same amount of horizontal space. They are often used to display code. Cursive - These typefaces emulate a human handwriting style and are often used sparingly for a personal touch.
