Personalised correspondence can significantly impact the recipient because it shows that you have taken the time to consider their needs and preferences. It can help build trust and rapport, making it essential to business communication.

Incorporating a personal touch into your correspondence can strengthen relationships and enhance your professional image. Personalised correspondence, whether handwritten notes or carefully crafted emails, can make a lasting impression.

Best Practices for Business Correspondence

Effective business correspondence is not just about conveying a message; it’s about doing so clearly and professionally in a way that aligns with your company’s values. Here are some best practices to ensure your business correspondence is top-notch:

Clarity and Conciseness

  • Be Direct: Get to the point quickly. Readers should understand the main message within the first few lines.
  • Avoid Jargon: Use simple language and only technical jargon if you are sure the recipient understands it.
  • Short Sentences: Keep sentences short and to the point to enhance readability.
  • Structured Layout: Use bullet points, headings, and paragraphs to break up text and make scanning easier.

Professional Tone

  • Formal Language: Use formal language in all business correspondence. Avoid slang and overly casual language.
  • Politeness: Always be polite. Phrases like “please,” “thank you,” and “could you please” go a long way in maintaining a professional tone.
  • Neutral Tone: Maintain a neutral tone, especially when dealing with sensitive or contentious issues. Avoid emotional language or anything that could be interpreted as aggressive or confrontational.


  • Check Grammar and Spelling: Errors can undermine your professionalism. Always proofread your correspondence for grammatical and spelling mistakes.
  • Read Aloud: Reading your text aloud can help catch errors and awkward phrasing.
  • Peer Review: If possible, have a colleague review your correspondence before sending it, especially for essential communications.


  • Branding: Ensure your correspondence is consistent with your company’s branding.
  • Formatting: Use a standard format for all business correspondence.
  • Tone and Style: Maintain a consistent tone and style across all types of correspondence. This will help reinforce your company’s professional image.

Use of Templates

  • Standard Templates: Use templates for common types of correspondence.
  • Customisation: While templates are helpful, always customise them to address the recipient’s needs and situation.

Appropriate Channels

  • Choose the Right Medium: Use the appropriate channel for your message. Emails suit most business communications, but more formal documents might require printed letters.
  • Timeliness: Send your correspondence promptly. Delayed communication can lead to misunderstandings and missed opportunities.


  • Sensitive Information: Be cautious when sharing sensitive information. Ensure that confidential data is protected and shared only with authorised individuals.
  • Secure Channels: Use secure communication channels for sensitive information. Encrypt emails if necessary.


  • Acknowledge Receipt: When you receive essential correspondence, acknowledge it promptly.
