What Is A Professional Thank You Letter?

A professional thank you letter is your expression of gratitude for a job interview or a sales call. Even though it is necessary to send thank you notes in these circumstances, they can be used for other reasons as well. You can thank people for their help in a job search or for referring you to their contacts and HR managers.

Thank you letters play a crucial role in professional life. They can be useful in different ways. You can keep in touch with your contacts, or remind the selection committee that you are the right choice for the job. These letters also convey the message that you are aware of professional etiquette, which can help your career advancement.

The mode of communication and format is very important in thank you letters. Ensure that you are clear about what you want to say, and you can decide whether to send the thank you as a card, a letter or an email. The right channel creates a lasting impression, and the recipient feels appreciated as well.

Types Of Professional Thank You Letters

There are primarily three types of thank you letters, as mentioned below:

  • Email: This is the preferred mode of communication in the business world, currently. For a prompt response, email is your best option. For example, you can thank the interview panel for a job opportunity to create a positive impact before they make their final decision.

  • Printed thank you letters: There are typed letters, which should communicate the message that you know the company and the person you are addressing. You can send a handwritten note or a typed letter written in a formal or informal tone depending on the recipient. A written thank you note conveys the message that you are sincere in expressing your gratitude.

  • Handwritten thank you letters: Traditional companies like typed or handwritten letters. A handwritten card is best for personalised messages or if you are thanking a former colleague.

How To Write A Professional Thank You Letter?

All thank you letters should contain some essential points. Here are the steps to write your letter:

  1. Address with a proper salutation. Start with a proper salutation, such as Dear Mr. or Dear Mrs. as required. If you know the person very well, write his or her first name, otherwise use their last names. Some examples include Mr. Rathi, Mrs. Roy or Ms. Latha.

  2. Start with 'thank you.' Try to be straightforward and say thank you in the first few sentences, so the person knows the purpose of your letter. If you are communicating via email, the subject line should contain 'Thank you.'

  3. Mention some details. The person should know the reason for your appreciation. For example, if you are thanking a person for their advice in a job search, talk about the most helpful tip. If you are saying thank you after a job interview, do not forget to mention why you are the right candidate for the job. Some specific details make it easy for the person to know what you liked the most and why.

  4. Say thank you once again. This is important to add before signing off to follow etiquette.

  5. End with an appropriate closing remark. Professional closings include 'Best regards' or 'Sincerely.' Insert your signature at the end in one of the three formats: type it in or use a digital signature if it is an email, type the name and sign it in the space above your typed name if it is a printed letter or sign it manually in case of a handwritten card.

Tips For Writing A Good Thank You Letter

Timing plays a crucial role in all thank you letters. They should be sent as soon as possible, particularly after a job interview, because doing so increases your chances of getting the job. Here are some more tips for writing a good thank you letter:

  • Express your sincere gratitude. For example, if you are thanking a colleague for their help in a project, try to express how their assistance made things easier for you to complete the project in time. For example, you can write, 'Dear Lakshmi, I am writing to express my heartfelt thanks for staying late to help me complete my sales calls. Because of you, I was able to meet my quota for the month.'

  • Personalise each letter. Personalisation creates a sense of familiarity and earns goodwill for you. For example, the inclusion of particular points of conversation in your thank you note strengthens the bond of the relationship between you two. As one example, you could write, 'Dear Mr. Laghari, thank you for interviewing me for the project manager role. I enjoyed learning that you also went to Jawaharlal Nehru University.'

  • Make it short and sweet. Write short and sweet thank you letters. Your letter should end in a few brief paragraphs.

  • Keep it error-free. A thank you letter must be professional, well written and free of any mistakes. Read it two or three times carefully before sending it.
