When colleagues provide you with major help at work, lend a hand when you're in a jam, assist with a challenging project, or generally go above-and-beyond what's required, it's a kind gesture to send a letter of appreciation. You can also send a note or email message to a colleague who has covered for you while you were out sick or on leave.
Why Send an Appreciation Note
Sending a letter of appreciation lets colleagues know that their hard work and help is noticed and valued. Everyone likes to know that they are appreciated. Plus, taking the time to show that you've noticed always makes a good impression. Expressing your appreciation also helps to build and maintain a work climate that is positive and congenial.
Who to Thank and When to Say Thank You
If you are leading a team, you might want to send out a team-wide email of thanks when you pass key milestones and, ultimately, complete a project. Team members who feel that their contributions have been publicly affirmed are much more likely to give their best effort than those who never hear a word of praise and think that they are being taken for granted.
If you are a new employee fortunate enough to have attracted a volunteer mentor, by all means, you should write a note to thank your mentor for taking time away from his or her own workload to help you with yours.
If you are emailing a co-worker, you can also copy the person's manager.
It's always nice to let people with power over promotions and raises know when their employees are performing well. Recognition of an employee's assistance helps promote his or her value to management.
An email is the quickest way to say thank you, but a handwritten note or letter always makes a good impression. It shows that you have taken an extra step to show your appreciation for the assistance provided by a colleague at work.
Regardless of how you opt to say thank you, do take the time to let those who have assisted you at work know that they're appreciated.

I’m extremely fortunate to have you as a colleague, and I look forward to the day when I can follow the example you’ve set in helping our new hires feel grounded and supported.
Tips for Writing Your Appreciation Letter
When you write a thank-you letter to a colleague, opt for a more formal than casual tone. That's especially important if you are copying managers and colleagues on the letters. A breezy "Thanks for the help" email is nice, but spending the time to make sure the letter is well constructed may feel more meaningful.
Your Letter Should Be Genuine: Avoid excessive flattery, which can seem insincere. Be specific in your praise, and explain exactly why you are writing the letter. No need to overthink your message — the most important thing is to make sure you say "thank you" in the letter. Before you send your letter, proofread it to make sure you do not have any typos.
Be particularly careful to make sure you've spelled the recipient's name correctly.
Don't Delay Sending Your Thank-You Letter: While you do want the message to be thoughtful, it's also important to not let too much time pass between the event or favor that warranted thanks, and you sending your letter.

Be genuine, and not too effusive, in your message. Whether you're sending a handwritten or emailed note, aim to be authentic and sincere.
