Do we write email or e mail

Both "email" and "e-mail" are acceptable ways to refer to electronic mail. The difference lies in the style guide you're following.

"Email" is the more commonly used and preferred form in modern English. It's the way most people write and read it. The Oxford English Dictionary, Merriam-Webster's Dictionary, and many other style guides recommend using "email" as the preferred form.

"E-mail", on the other hand, is still widely used, especially in formal or technical contexts. This form was more commonly used in the past, especially when the term was first introduced. Some style guides, like the Chicago Manual of Style, still recommend using "e-mail" as the preferred form.

So, to answer your question:

• If you're writing for a general audience or in a casual context, "email" is a safe choice.
• If you're writing for a formal or technical audience, or if you're following a style guide that recommends "e-mail", you can use that form.

In the end, both forms are widely understood, and the choice ultimately comes down to personal preference or the style guide you're following.
