In the case of a simple, short note, you should make sure the paper is small too. A few sentences scrawled on a big sheet of paper will look uninvolved. Post-it notes are usually small and perfect for quick thank-you notes.
Include your name, the date and the addressee at the top of the letter. Type using a standard font (such as Times New Roman) and size (12). Include your signature at the bottom. This will give even a typed letter a personal touch.
Compared to a simple note, you can go into more detail about what you’re thankful for with a professional letter, and explain how their part has benefited you. For example, if he vouched for you at a meeting, you can expand upon your gratitude by noting all the career doors their support has opened for you. For example: “I am writing to thank you for the help you offered at the board meeting today. The advice would offered to me beforehand proved invaluable, and the professionalism, work ethic and integrity you exhibit on a daily basis is a true example for the rest of the company to follow. "”
For example, if the recipient helped you through openly vouching for a project idea of yours, you can explain specifically how that will help you in the long run: “Thanks to you vouching for me, I’ll have my chance to show what a capable and innovative worker I am. I am confident that this tentative project will be a great success, and I am certain they’ll want to see a lot more of me once it’s done!”
For example: “P. S: If this interview goes through, I’ll buy us a round at the pub this weekend! Or, if you and the recipient are on equal footing in the career hierarchy: “P. S: I’ll make sure to do the same for you next time! Together we’ll be heading straight to the top!”
If you’re having any confusion regarding whether your letter works or not, try reading it out loud. You’ll find reciting the letter (or any written document, for that matter) will bring attention to issues and areas for improvement you wouldn’t normally pick up from reading alone.
Using a pen with legible handwriting is preferable in this case.
For example, if the recipient gave you advice on an upcoming job interview, you can say: “I’d like to thank you for all the advice you imparted regarding the interview. I’m going to keep it in mind while I’m preparing for it; I’m confident it will help me land the job!”
If space on the page is an issue, you can just go the formal route and write the date in shorthand (e. g. 09/27/15).
Although it’s not a likely risk in a professional note, it’s a good idea to exercise some discretion with a note. Assume that anyone could potentially read it, especially if you’re leaving it in a high-traffic area like the office space. If there is any doubt, it’s best to seal your letter in an envelope.
If you attach a gift, it is best to deliver the letter and gift personally.
If you’re feeling anxious, take a moment to remember the fact that very few people have felt anything other than gratitude and satisfaction for being thanked for something!
