Professional Thank You Letter Examples and Writing Tips

The importance of professional thank you letters in the business world can never be overstated. Besides expressing gratitude to the recipient(s) for whatever favor they’ve done you, a thank you letter brings the sender a wide variety of benefits. For example, a thank you letter after a job interview has the potential of significantly setting you apart from the other applicants fighting for the position you are gunning for, thereby increasing your chances of getting the job.

There are various kinds of professional appreciation letters for different groups of people in the corporate world. So without further ado, let’s look at samples of these letters and some of the important writing tips you should have at your disposal when writing such a letter.


Tips for Writing Professional Thank You Letters

Here are some important things you need to take into consideration whenever you are penning a professional letter of appreciation:

  • Speed is of the essence. It is imperative that you send the thank you letter to the recipient as soon as possible. Don’t wait until several days or weeks after the favor has been done you before sending your appreciation. The earlier you send the letter, the better the recipient’s memory is of what they did for you to warrant a thank you.
  • Always start with a salutation. It is never advisable to begin your letter with the person’s name as this can be seen as very rude. While there are a number of salutations you can use in beginning a letter, the best salutation to use for professional-related correspondence is the word “dear”. For example, “Dear Sir” or “Dear Mr. Bolton”. In the event you don’t have a contact person you are writing to at the company or organization, you can use any of the following general salutations: “Dear Sir or Madam”, “To Whom It May Concern”, “Dear Human Resources Manager” or “Dear Hiring Manager”. FYI: The latter two salutations are only used if you are dealing with employment-related correspondence.
  • State the reason(s) for saying thank you. Try to make it as clear as possible what you are thanking the recipient for. For example, if the recipient took time out of their busy schedule to interview you for a job, state it and thank them for their time.
  • Sincerity is the name of the game. Always be sincere when expressing your gratitude. Insincerity can be easily detected. So be mindful of that.
  • Don’t write a novel. The last thing you want to do in an appreciation letter is to make it lengthy. Always endeavor to keep your thank you letter as concise as possible. Two or three short paragraphs would do just fine.
  • Close your letter. This is basically your last sign off. All letters need to be closed. Some of the most common traditional terms used in closing professional letters include “Yours truly”, “Sincerely”, “Yours sincerely”, and “Best regards”. Having used any of these terms, you should follow it with a comma, sign your signature (if you are sending a hardcopy letter) and add your full name. However, if you’re going to be sending your letter as an email, you can forgo the signature part and type your full name beneath the closing. FYI: A closing is one of the most important elements of every letter! Never send a letter that is devoid of one. Having said that, it’s worth taking note of the fact that not all closings are appropriate for a professional letter. Some of the inappropriate closings you should never use include: “Cheers”, “XOXO”, and “Love”. These terms are perfect for closing a letter you are writing to someone whom you are very close to but certainly not a business letter.
  • Edit and proofread it multiple times. Don’t just send your letter to your recipient the moment you are done writing it. Take your time to thoroughly proofread it a number of times before sending it. The proofreading process will see you checking important things such as typos, spellings and grammar. After you are done proofreading your letter yourself, you can even take things a step further by asking a close friend to proofread it again. That way you will be 100% sure that you have in your possession an absolutely perfect letter free of errors.

Types of Thank You Letters

The following are some of the most popular types of professional thank-you letters:


Thank you letter after job interview

These letters are sent to your potential employer(s) after they have interviewed you for a job. These letters are considered one of the most important elements of any job-hunting strategy that you embark on. Since more often than not, you are not going to be the only applicant being interviewed for a job, it is imperative that you do whatever you can to stand out from the crowd. And that’s where a thank-you letter becomes very useful In addition to acting as a medium to express your gratitude, this follow up letter allows you to build a closer relationship with your interviewer(s) while helping you separate yourself (in a positive way) from the rest of the candidates chasing after the vacant position.

Interview thank you letter tips

  • Start by thanking whoever interviewed you.
  • Since this is a letter to show appreciation, it doesn’t necessarily need to be formal. It should just be sincere, thoughtful and nice.
  • Slightly talk about the reasons why you feel you are the best applicant for the job. However, in doing so, remember not to stress too much on that. Remember that you’re just writing to show your appreciation, not to market yourself.
  • Try as much as possible to reiterate your interest in the vacant position. This is very important.
  • If there was something very important you forgot to mention during the interview, this letter is the best place to put that additional information.
  • End by sincerely thanking the interviewer(s) once again for their time and offer to supply them with any additional information they might need from you.
  • With thank-you letters, the more you write from your heart, the better your letter is going to be. So try doing that.
  • Your letter shouldn’t be very lengthy. Experts say writing a couple of paragraphs would do just fine.
  • Proofread your letter again and again. This can’t be said enough. Double check your grammar, spellings, punctuation, etc. Also make sure that you have spelled the recipient’s name correctly.

So all in all, no matter which angle you to choose to look at it from, job interview thank-you letters can help you make a good impression, set you apart from the competition, and increase your likelihood of being considered for a job if you take your time to write them well, considering the fact that only a tiny fraction of applicants bother to send thank you letters.
