You know the drill: You get all dressed up, show up prepared as ever, nail your interview (thanks, in part, to these killer HR tips), and then鈥 nothing. You send a thank you email, but it seems to be to no avail: That once eager headhunter is NOT getting back to you.

You鈥檝e followed all these steps, so you know they at least READ it鈥 so what gives? According to a new study by Boomerang, it may be that you simply didn鈥檛 leave a lasting enough virtual impression.

In an analysis of 350,000 emails from 20聽different online communities (sheesh!), Boomerang found a direct correlation to email closings and response rates. Of the eight most popular sign-offs in a formal situation (no 鈥淟ove you baby鈥漵 here!), one closing in particular outshone the others in the top spots by as much as 14.5 percent. Check out the difference below:

RESPONSE RATES OF EMAIL CLOSINGS

8. 鈥淏est鈥 鈥 51.2 percent

7. 鈥淏est regards鈥 鈥 52.9 percent

6. 鈥淩egards鈥 鈥 53.5 percent

5. 鈥淜ind regards鈥 鈥 53.9 percent

4. 鈥淐heers鈥 鈥 54.5 percent

And the top three?

3. 鈥淭hank you鈥 鈥 57.9 percent

2. 鈥淭hanks鈥 鈥 63 percent

1. 鈥淭hanks in advance鈥 鈥 65.7 percent

Notice a trend here? As Boomerang notes, 鈥淐losing with an expression of gratitude鈥 correlated with a whopping 36.5 percent increase in average response rates (47.5 percent) compared to signing off another way.鈥

What鈥檚 more, a similar study in 2010 entitled 鈥淎 Little Thanks Goes a Long Way鈥 saw 69 students being split into two groups to write an聽email requesting help with a cover letter. One half was instructed to include the line, 鈥淭hank you so much!鈥 while the other half did not. Guess which side got double the responses?

Huh. Who knew that all our potential employers (and everyone else) were after was a little thanks?
