It comes from the Greek word apostrephein which means "to turn away." You are already familiar with the punctuation mark known as the apostrophe.

A valid email address consists of an email prefix and an email domain, both in acceptable formats. The prefix appears to the left of the @ symbol. The domain appears to the right of the @ symbol. For example, in the address example@mail.com, "example" is the email prefix, and "mail.com" is the email domain.

2 Answers. They are both correct. The use of an apostrophe to form a plural of a mentioned term (which is what you would be doing here) is valid, though less commonly used than it used to be.

Short answer: No! If you happen to capitalize your email address, or your autocorrect simply messes up, fear not. ... Unlike passwords, email addresses are not case sensitive. Whether or not you add capitals, your email server will read it the same way as long as the numbers and letters match your official email address.

3 Answers. Yes, they are valid characters as long as the mail exchanger responsible for the email address supports the UTF8SMTP extension, discussed in RFC 5336. Beware that just a small portion of the mail exchangers out there supports internationalized email addresses.

The domain name part of an email address is case insensitive (i.e. the case does not matter). ... The email address ReCipiENt@eXaMPle.cOm is indeed different from recipient@example.com (but it the same as ReCipiENt@example.com). Simply put: Only the username itself is case sensitive.

Avoid hyphens if possible But, keep in mind that use of hyphens also strongly correlates with spammy behavior and decreases domain name readability and memorability. For that reason, generally, no more than one hyphen should be used (if any must be used at all).

Users should always consider that URLs are case-sensitive. All “insensitive”s are boldened for readability. Domain names are case insensitive according to RFC 4343.

Adding an apostrophe makes the last name possessive, which is unnecessary in this case. ... Leave out the apostrophe when making last names plural. For names that do not end in –s, –z, –ch, –sh, or –x, just add –s to the end of the name to make it plural.
