What formatting technique is suggested for lengthier emails to improve readability?

Using bullets in lengthier emails significantly enhances readability by breaking down complex information into digestible pieces. This technique helps distill key points and ensures that the reader can quickly identify the main ideas without sifting through large blocks of text. Bulleted lists create a visual hierarchy, allowing for a straightforward presentation of information that can be scanned easily. When conveying several pieces of information, especially if they are related but require individual attention, bullets allow each item to stand out clearly.

On the other hand, while bold text can emphasize particular words or phrases, it does not inherently improve the overall structure of a long email. Avoiding paragraphs would make the email less organized and harder to follow, as chunks of text without breaks can overwhelm the reader. Using colored fonts can draw attention but may also distract or confuse the reader if not used judiciously, potentially detracting from the message rather than supporting clarity. Thus, the use of bullets is the most effective formatting technique for maintaining readability in longer emails.
