When communicating assertively in emails, you can build self-confidence at work. To do this, be clear and concise. Use a clear subject line, a polite greeting, and a brief introduction. State the purpose and the main message of your email in the first paragraph. Utilize bullet points, headings, and formatting to organize your information. End with a call to action and a courteous sign-off. Respectfully use a formal or neutral tone, and avoid slang, jargon, and emoticons. Ensure proper grammar, spelling, and punctuation. Refrain from using all caps, bold or colored fonts. Exercise caution when using humor, sarcasm, or irony as they may be easily misunderstood or misinterpreted. Employ assertive language such as "I would like", "I request", or "I suggest", rather than passive or aggressive language like "You should", "You must", or "You failed". Choose positive words like "please", "thank you", or "appreciate" over negative words like "sorry", "unfortunately", or "regret". Utilize phrases that show confidence such as "I am confident", "I am sure", or "I look forward to" instead of phrases that show doubt such as "I hope", "I guess", or "I wonder".
