Email or E-mail? The Correct Spelling Explained

You are about to send a job application, and you pause at one small word: should it be “email” or “e-mail”?

Both spellings are correct. They mean the same thing, sound the same, and work the same way in a sentence. The only difference is the hyphen.

Email, without the hyphen, is now the more common form, but some style guides and publications still prefer e-mail.

The hyphenated form comes from the “e” in “electronic,” the same “e” you see in e-commerce and e-book.

This guide shows when to use each spelling, how to use the word as a noun and a verb, and which mistakes to avoid.

Quick Answer: Email or E-mail?

Use email by default. Use e-mail only if your school, employer, or publication tells you to. Whichever you choose, stay consistent throughout your writing.

What Does Email Mean?

Email is short for electronic mail. It can mean two things:

The system used to send messages over the internet (“I prefer email to phone calls.”)
An individual message (“I received an email from my manager.”)

The same word also works as a verb: “Please email me the details.”

Why Are There Two Spellings?

The hyphenated form came first. When electronic messaging was new, writers used e-mail to show that the word joined two parts: electronic and mail. This matches other “e-” words such as e-commerce, e-book, and e-learning.

As email became part of daily life, people stopped treating it as a technical term and started writing it as one ordinary word. Many compound words follow this path. They begin with a hyphen and later become a single word once readers are familiar with them.

Today both forms are accepted, but the one-word spelling is more popular. Many major style guides now prefer it, including AP Style, Microsoft’s style guide, and Oxford University’s guide.

Email vs. E-mail at a Glance

Feature	Email	E-mail
Spelling	One word	Hyphenated
Meaning	Electronic mail	Electronic mail
Pronunciation	Same	Same
Used as noun and verb	Yes	Yes
Modern usage	More common	Still accepted
Best for	General writing	When a style guide requires it

Which Spelling Should You Use?

In American English

Choose email for blog posts, school assignments, business messages, and general writing. It is simple, familiar, and matches current style guidance. If your teacher, editor, or company style guide asks for e-mail, follow that instead.

In British English

There is no rule that one spelling belongs to America and the other to Britain. Both forms are recognized in both varieties of English. The right choice depends on the publication or organization you are writing for.

In Formal Writing

Some older advice says the hyphenated form is safer in formal documents. That is no longer true, because most modern style guides accept or prefer the unhyphenated form. Your style guide should make the decision, not how formal the document sounds.

How to Use Email as a Noun and a Verb

Email as a Noun

As a noun, email names a message or the system used to send messages.

I received an email yesterday.
She sent three emails this morning.
Email is the easiest way to reach the team.

Email as a Verb

As a verb, email means to send someone a message electronically.

I will email you tomorrow.
Please email the report to your manager.

Verb Forms

Form	Example
email	I will email you.
emails	She emails her clients every week.
emailed	He emailed the report.
emailing	They are emailing the team.

If you prefer the hyphenated style, the forms are e-mails, e-mailed, and e-mailing.

Is It “a Email” or “an Email”?

It is an email. The word begins with the vowel sound “ee,” so it takes “an.”

Did you send an email to the client?
I haven’t received an email since Monday.

The same rule applies to the hyphenated form: an e-mail.

Should You Capitalize Email?

No, unless it starts a sentence. Email is a common noun, like “letter” or “phone.”

I don’t check my emails on weekends.
Email is my preferred way to communicate at work.

Email vs. Mail: What Is the Difference?

Mail refers to physical letters and parcels sent through the postal service. Email refers to electronic messages.

I need to pick up my mail from the post office.
I will send you the file by email.

People sometimes use “mail” informally to mean electronic messages, but it can confuse readers. When you mean an electronic message, write email.

Examples of Email and E-mail in Sentences

Using email:

Please check your email for the confirmation.
I forgot to reply to your email.
My email address is on the form.
She emailed me about the meeting.

Using e-mail:

Please check your e-mail for the confirmation.
I forgot to reply to your e-mail.
My e-mail address is on the form.
She e-mailed me about the meeting.

Each pair says exactly the same thing. Only the spelling style changes.

Common Mistakes to Avoid

1. Writing “e mail” with a space

“E mail” is not an accepted spelling. Write email or e-mail.

❌ Please send me an e mail.
✅ Please send me an email.

2. Thinking “e-mail” is wrong

The hyphenated form is not an error. It is simply less common today.

3. Mixing both spellings in one piece of writing

Switching between the two looks careless.

❌ I got your email yesterday. Please reply to my e-mail today.
✅ I got your email yesterday. Please reply to my email today.

4. Confusing an email with an email address

An email is the message. An email address is where the message is sent. “I sent you an email” and “Please share your email address” are different things.

5. Using “a email”

Always use an before email.

An Easy Way to Remember

Think of the “e” as electronic. Electronic letter means email. Physical letter means mail. As for the hyphen, remember one rule: pick one spelling and stick with it.
