Avoid the Delete Key

Your font size should be a minimum of 10 point. Format your e-mails to a tight width of 500 to 600 pixels. Reading on a computer screen is a different experience. It’s much harder for the eye to scan across the entire width of the screen.

As for background colors, most e-mails that present multiple items use a white background or a very light tint. If you’re to use a black background for an offer box, be sure to bump up the font size even more.
