Thank You Letter For Help. Thank You Letter for Support: Every gesture in life is important and when someone does something good for you it becomes equally important to thank them for the effort and initiative they have taken for you. 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.

A thank you letter may be formal or informal written to family members, friends, colleagues, or to any person in the world who has helped you at some point, somewhere and for which you are highly obliged to that person.
It gives you a chance to show that person you recognize what they did.
All the candidates that you had. What a wonderful thing for your friends to do for you! You can send a thank-you letter after.
