Blind Carbon Copy (BCC)
BCC is a feature in email that lets you privately send a message to someone. When you add an email address to the BCC field, the BCC recipient receives your message like everyone else, but their email address is hidden from the main recipients and from any other BCC recipients. In other words, they’re invisible on the “To” and “CC” lines.
In marketing, automated messages can be set to include a BCC line for tracking or compliance reasons. For instance, a copy of client communication might be BCC’d to a CRM-connected address to log the message automatically.
