Many online sites generate a customized address for you like CAeporFsks2373454-submission@myblogging.com. You may write an email to that address and what you write in the body of that email gets published or entered in a database.
Some sites like Trello refer to it as "your email" but it is not 'your' email account (e.g. From: amanda23@hotmail.com) but a dummy electronic mail address you are supposed to write to (To: CAeporFsks2373454-submission@myblogging.com).
