When spelling out e mail say dash or hyphen

When spelling out "e mail" in written form, it's common to use a hyphen (-) instead of a dash (- -). This is because a hyphen is a shorter punctuation mark that is specifically designed to connect two words or parts of a word, whereas a dash is a longer punctuation mark that is often used to indicate a break in thought or to set off a parenthetical remark.

So, when spelling out "e mail", you would typically write it as "e-mail". This is the most common and widely accepted way to write it.

It's worth noting that some style guides, such as the AP Stylebook, recommend using a space between the "e" and the "mail" when writing out the phrase, like this: "e mail". However, the majority of style guides and dictionaries, including the Oxford English Dictionary and Merriam-Webster's Dictionary, recommend using a hyphen to connect the two words.
