商務英文郵件的寫法講究多多，結尾的問候語在不同場合也應使用不同的字眼。福布斯職場專家蘇珊·亞當斯和禮儀顧問萊特為我們總結了以下郵件結尾（email sign-offs），并附上了用法解釋。

Best

This is the most ubiquitous; it's totally safe. I recommend it highly and so do the experts.
最普遍；最安全。我和專家們都極力推薦這個。

My Best

A little stilted. Etiquette consultant Lett likes it.
有點生硬。禮儀顧問萊特喜歡這個。

My best to you

Lett also likes this one. I think it's old-fashioned.
萊特也喜歡這個。我認為它過時了。

All Best

Harmless.
可以用。

All the best

This works too.
這個也可以。

Best Wishes

Seems too much like a greeting card but it's not bad.
看起來特別像賀卡，但是還不賴。

Bests

I know people who like this but I find it fussy. Why do you need the extra "s"?
我知道有人喜歡，但是我覺得它很繁瑣。為什么你需要多余的“s”？

Best Regards

More formal than the ubiquitous "Best". I use this when I want a note of formality.
比最普遍的“Best”更正式。當我想要正式的寫結尾時我會用這個。

Regards

Fine, anodyne, helpfully brief. I use this.
不錯，穩(wěn)重，簡短。我用這個。

Rgds

I used to use this but stopped, because it's trying too hard to be abbreviated. Why not type three more letters? OK if you're sending it from your phone.
我過去常用這個但是現(xiàn)在沒用了，縮寫太過了點。為什么不多寫幾個字母？如果是用手機發(fā)郵件的話，這個OK 。

Warm Regards

I like this for a personal email to someone you don't know very well, or a business email that is meant as a thank-you.
我喜歡在給不是很了解的人發(fā)私人郵件時用這個，或在商業(yè)郵件里表達謝意。

Warmest Regards

As good as Warm Regards, with a touch of added heat.
跟Warm Regards一樣好，且更增添了一絲溫暖。

Warmest

I use this often for personal emails, especially if I'm close to someone but not in regular touch.
私人郵件中我常常用這個，尤其是當我跟某人比較熟但又不常聯(lián)系時。

Warmly

This is a nice riff on the "warm" theme that can safely be used among colleagues.
這是一個關于 “warm” 主題很好的結尾，在同事之間使用很安全。
