If you send a message to JaneDoe@gmail.com with mixed case or to janedoe@gmail.com in all lower case, does is make a difference? What about Jane@myabccompany.com or jane@MyAbcCompany.com?

Email addresses are not case sensitive. You can address your message in all lower case, upper case, title case, or mixed case. The message will go to the same person and you won’t get a bounced notification.

Title case is frequently used simply for ease or reading or recognition.
