- 30 common email abbreviations you should know
- Conclusion

So, a few days back, one of my team members sent me an email with the subject line. *“Need your reviews on the latest marketing report. VSRE”*

So, I didn’t pay much attention to the abbreviation, wrote a long review, and ended the email by asking her, *“What does VSRE mean anyway?”*

Her response was: *“Very short reply expected.”* 😃

Oops! I felt so embarrassed doing exactly the opposite.

To avoid going through such embarrassment again, I compiled all the frequently used **email abbreviations and acronyms.** And if you have gone through something similar, you will know what exactly I mean.

Whether you're writing internal emails or sending campaigns through an [email marketing platform](https://www.mailmodo.com/), knowing these abbreviations can save you from confusion and improve clarity.

So in this guide, you will find every email abbreviation you should know of.

## 30 common email abbreviations you should know

Here is a list of **email abbreviations and acronyms** that you can use in your emails:

### 1. AB - Action by

### 2. AR - Action required

Used to inform the recipient that they are given a task.

### 3. BCC and CC - Blind carbon copy and Carbon copy

You can see both these acronyms in your email program. You use them when you want to send a message to the main addressee and other interested parties.

The email address in the CC field will be visible to every recipient of the email, but those in BCC will not be.

So, if you don't want everyone to see all of the recipients of a message, you would enter their email addresses in the BCC field.

### 4. EOD - End of day

It is used when you want to send or receive something by the end of the day.

### 5. EOM - End of message

### 21. OOO - Out of office

When you send documents or a set of documents in the email, you should mention PFA to inform the recipient about the documents.
