Questions: Which of the following is a best practice for formatting an email? Use fancy formatting. Use of specialized fonts. Use a simple and common font Bolding key information.

The answer is: Use a simple and common font.

Explanation for each option:

1. Use fancy formatting: This is not considered a best practice for formatting an email. Fancy formatting can be distracting and may not display correctly on all email clients or devices. It can also make the email look unprofessional.

2. Use of specialized fonts: Similar to fancy formatting, using specialized fonts is not recommended. Not all email clients support specialized fonts, and if the recipient's email client does not support the font, it may default to a less readable font. This can affect the readability and professionalism of the email.

3. Use a simple and common font: This is the best practice for formatting an email. Simple and common fonts like Arial, Times New Roman, or Calibri are widely supported across different email clients and devices. They ensure that the email is easy to read and looks professional.

4. Bolding key information: While bolding key information can be useful to highlight important points, it should be used sparingly. Overuse of bolding can make the email look cluttered and reduce its overall readability. It is a good practice but should be combined with the use of a simple and common font for the best results.
