Email or e mail which is correct

Both "email" and "e-mail" are acceptable and widely used, but there is a slight difference in their usage.

"Email" is the more commonly used and preferred form in modern English. It's a single word, and it's often used as a noun, verb, or adjective. For example:

"E-mail", on the other hand, is the original form that was used when the term was first introduced in the 1970s. It's still widely used, especially in formal or technical contexts. For example:

In general, if you're writing in an informal setting, such as a blog post, social media, or a text message, "email" is the way to go. If you're writing in a formal setting, such as a business letter, academic paper, or technical document, "e-mail" might be a better choice.

So, to summarize:

Now, go ahead and send that email (or e-mail, if you prefer!)
