What happens if you send an email to the bcc?

When you send an email using the BCC (Blind Carbon Copy) field, the recipients included in the BCC list receive the email without seeing the addresses of other BCC recipients. This ensures privacy, as each BCC recipient is unaware of who else received the email. Recipients in the "To" and "CC" fields can see each other's email addresses, but the BCC recipients remain hidden from everyone else.
