商用電郵大多以客套話為開首，而客套話其中一種通用的做法，就是首先針對雙方的關係答謝。
Pleasantries（客套話）：無論是B2B（Business-to-business） 或是B2C （Business-to-consumer） ，商用電郵首部分不是要說出主題，而是表達感謝，當然這部分也不宜過長。一、兩句客套話便足夠了。商業電郵跟普通電郵不同之處，是後者一向注重簡約及到點。
1. IT’S A PLEASURE：
- 例如：Mr. X, it has been a pleasure of ours to have you as our esteemed client.
- 例如：Ms. X, it has been a distinct pleasure to have you on board.
保持客氣而得體態度
2. THANK YOU：
- 例如：I would like to thank you personally for your continued patronage（惠顧）.
- 例如：We would like to extend our sincerest thanks for your support.
- 例如：Thank you once again for taking the time to review our email.
Main points（主要內容）無論是商業信件或是個人信件，均一定要明確地道出想表達的內容。因此，建議將主要內容放置在信件的第二段，跟客套話分開。主要內容要簡約，語氣亦要保持客氣。
3. THE FIRST THING I WOULD LIKE TO BRING TO YOUR ATTENTION IS：
- 例如：The first thing I would like to bring to your attention is the matter of our upcoming campaign. Here are the details…
4. AS A WARM REMINDER, PLEASE KINDLY NOTE：
- 例如：As a warm reminder, please ……
Call to action（信後的行動）：無論你商用電郵的目的是sales/marketing或者告知，信件裏面亦應該明確地指示對方之後的course of action（行動方針）。如果電郵是關於sales/marketing的，你會否提供一個途徑，邀請他們訂閱你們的服務？如果這個電郵是關於某些邀請目的，那麼信件一定要寫明需要他們回覆。
在現今的電子社會文化，如果電郵裏面沒有清楚地說明信後的行動，一般來說，收信者都不會作出任何follow up（跟進）。以下有幾個客氣的例子。
DIRECT（直接的做法）：
5.WE KINDLY REQUEST THAT YOU：
- 例如：We kindly request that you would subscribe to our service. You may do so through clicking this link right here: www.example.com. Thank you for your attention.
- 例如：As a kind request, please fill out the attached questionnaire and submit your response before April XX, 2020. Thank you。
INDIRECT（婉轉的做法）：
6. WE HOPE THAT YOU WOULD CONSIDER：
- 例如：We hope that you would consider contacting Mr./Ms. X to arrange a session soon at your convenience.
- 例如：It is our hope that you would consider offering your support by subscribing to our service by signing up here： www.example.com.
