Here are 2 fonts that make your emails readable - and 2 you should never use

Here are two fonts they recommend using:

• Georgia: Each letter written in this font has an additional stroke at the end. So it's generally easier to read the individual characters.
• Verdana: The shape of the letters in this font is more open than in fonts like Arial. There's additional space between letters, and the spacing is more even.

Here are two fonts they suggest not using:

• Helvetica: The letters are too close together, a type designer told Bloomberg. That makes it hard to read.
• Arial: Font designers say it has "ambiguous" letter shapes (as in, the letters "b" and "d" are the same shape in reverse) that make it hard to read multiple words in a row.
