Whether you want to send your newsletter from an email address that contains these characters, or between the accounts of your target clients exist accounts that contain these characters, we must consider several things.

On the one hand we must understand that an email address is divided into two parts, separated by the @:


The domain name must correspond to an existing domain, and must comply with the rules for domain names. These usually include letters, numbers, hyphens and periods (may exist domain names with ñ). Yoy can find more information on the following link https://en.wikipedia.org/wiki/Hostname

The local part can use any of the following characters:

– Uppercase and lowercase characters from the English alphabet

– Numbers from 0 to 9

– The following characters !#$%&’*+-/=?^_`{|}~

– The dot character “.” (but not at the beginning or at the end of the local part, or repeated twice)

– Certain special characters “(),:;<>@[]  with some restrictions

Note that the local part must comply with the provisions of the following article https://datatracker.ietf.org/doc/html/rfc5322, so that addresses that include:

– Latin Alphabet (with diacritics): Pelé@example.com

– Greek Alphabet

– Japanese Characters

– Cyrillic Characters

Might not work on all servers and mail clients.
