The speaker introduces the topic of email etiquette and the benefits of mastering it in the workplace.

• Email etiquette mistakes won't ruin a career, but mastering it can influence how capable one is perceived.
• There are no standardized courses for email etiquette, so the speaker aims to share personal tips.
• The speaker, Jeff, partners with Harvard Business Review to discuss a passion for email etiquette.

Poorly written emails can lead to confusion and unnecessary back-and-forth communication.

• A poorly written email can make it difficult to grasp the main point and scattered action items.
• This can result in a long email thread that could have been avoided with a well-planned initial email.

Effective emailing showcases strong communication skills and saves readers time.

• Well-crafted emails portray the sender as more capable and time-efficient for the reader.

Use specific call-to-action subject lines that include the task and the estimated time required.

• Instead of a generic 'action required', indicate the specific action and the time it will take.
• Examples include '5-minute survey feedback for project X' or 'Elon to approve spending estimates for Q4'.

Stick to one email thread per topic to provide context and avoid cluttering inboxes.

• Avoid sending separate emails for the same project as it leads to a lack of context and unnecessary inbox clutter.
• Use the original email chain for any given topic to keep all relevant information in one place.

Explain why recipients were added or removed from email threads at the beginning of the email.

• When changing the recipients, add a sentence at the top of the email to indicate the changes.
• Italicizing the font and using parentheses helps separate this information from the body of the email.

Start with the main point of an email before providing context.

• Avoid burying the main point at the end of an email; state it upfront followed by the necessary context.
• This approach respects the time of senior colleagues who may prefer to quickly understand the purpose of the email.

When replying to disorganized emails, summarize the sender's main points to confirm understanding.

• Identify and summarize the common themes in a disorganized email before responding.
• This confirms your understanding and shows appreciation for the effort to organize thoughts.

Hyperlink external websites or videos to keep emails clean and minimize the chance of errors.

• Use keyboard shortcuts to hyperlink text instead of pasting long URLs.
• Hyperlinking makes emails cleaner and reduces the risk of mistyping URLs.

Change the default email setting to reply to one person instead of reply all.

• Minimizing the impact of potential errors by limiting the audience with reply instead of reply all.
• This setting can be usually found in the general settings section of email clients.

Increase the undo send option to 30 seconds to catch and correct mistakes after sending an email.

• Mistakes are often noticed shortly after sending, so an extended undo send duration can be helpful.
• This setting is adjustable in most email applications and provides a safety net for corrections.
