You’ve just wrapped up your job interview and you feel it went great! While your excellent experience may have given you some confidence, you have no idea how all of the other interviews with job applicants went. So, in truth, you can’t really tell just how much you were able to stand out from your competition. This is a primary reason why following up with a thank you note is a great idea.

According to Monster.com, three out of four job seekers don’t send thank you notes. So, just imagine how much of an impact your thank you note will have on the hiring manager who interviewed you. The popular job search website cites an Accountemps survey of human resources managers to reveal that while only 24 percent of HR managers get thank you notes, 80 percent of them believe such notes are helpful when reviewing their candidates.

Is snail mail or email the way to go?

Since we’ve established sending thank you notes is a practical must-do for job seekers who are serious about landing their desired career opportunities, let’s discuss the ways in which you can send those notes. Either traditional snail mail or email is perfectly acceptable. Email, as you may have guessed, is the most popular method of sending thank you notes these days.

The same Accountemps survey found a whopping 94 percent of HR managers are just fine with receiving follow-up emails containing thank yous from job applicants. Monster notes, however, when deciding upon your thank you method of choice, it’s wise to consider the preferred methods of the company in question. How did the company first contact you? If it was by email, then you’re all set. If it was over the phone, you may want to consider a handwritten letter.

“Email thank-you notes have one clear advantage over their snail mail counterpart: It’s the quickest way to put your name back in front of the interviewer,” Monster.com points out, “However, you should also follow it up with a note in the mail to show that you aren’t Mr. or Ms. Casual.”

What are the main benefits of sending a post-interview thank you note?

Aside from the obvious kindness represented by the note and the whole “setting you apart from other candidates” thing, a thank you note can help you to correct a potential mistake. Do you feel like you may have flubbed the answer to a question? Do you wish to provide any further clarification about a point you made? Your thank you note offers you a great opportunity to patch things up.

On TheMuse.com, Sara McCord says writing thank you notes is a great idea for those who feel something odd happened during their interviews. She specifies a job applicant causing an interview to run long, as an example.

“By mentioning how much you appreciated the hiring manager’s willingness to answer all of your questions, you’re nodding to the fact that you know the meeting ran long (which is better than someone who just blows through allotted time),” says McCord, “And by saying you’d love to send on additional ideas for a question the hiring manger posed—you’re addressing the fact that your conversation was cut short for an unforeseen reason, but that you can roll with it and still provide valuable insights.”
