How to Write an Acknowledgment Letter

Since maintaining good relations with clients and associates is vital in today’s business environment, acknowledgment letters writing is highly important. An acknowledgment letter is a formal letter in which one person acknowledges and thanks another person for their time, trust, money or effort. It is an effective tool intended to maintain a good relationship with the people you deal with. Also, an acknowledgment letter can be written to inform somebody that the thing they sent has been received. It may be a copy of a document or receipt of payment. Business relationships often require conformation of an action from one party by another.

Apart from this, acknowledgment letters are considered as a specific category of thank-you letters aimed at acknowledging a contribution made or a gift given. Unlike thank-you notes, which typically focus on one short-term action, acknowledgment letters signify long-term actions, like the support of a relative or friend during a difficult period.


  • An acknowledgment letter should be brief and to the point.
  • The letter should be sent within two days of action prompting you to draft such a letter.
  • Be sincere. Try to be genuine in your letter, so that your recipient knows that you are not just completing a formality.
  • Address the letter to a person. Make sure that your letter is addressed to a specific person and not an organization or company in general. Business relationships are also built on personal interaction and human emotions.
  • Be polite. Start the letter on a positive note and maintain a courteous tone throughout the letter.
  • Use a letterhead. An official acknowledgement letter requires a company letterhead which can be on the top margin of the page, right, middle or left.


  • Mention any negative facts. Focus on your gratitude and appreciation.
  • Avoid over-praising or rambling. People usually know when you are insincere.
  • Passive voice too often
