I received an email from myself with a charge. Has my email been cloned? How to solve it? I get several charges from companies and banks that go to junk mail, but neither card I have.

This does not mean that your email account has been cloned. The protocol that defines the rules for sending and receiving e-mail does not have, at its base, any technology capable of guaranteeing the sender's authenticity.

In some cases, optional data that aids sender checking is not even sent along with the message – and that doesn't mean that any email is malicious (after all, the data is optional).

For this reason, the email service provider is unlikely to be sure that a message is fake and it will not erase or block it entirely. What the service does is to send the message to spam (junk mail). Some may escape the filter, and it's up to you to make it better.
