Email copy in AO is CC or BCC?

Just a small clarification: 
Email Copy: You can send copies of your email to a maximum of three recipients, which can be used for archival purposes. Click the Email Copy link to enter email addresses in the Email Copy to field, which is displayed after selecting Email Copy. You can choose to enter a static address or a lookup in this field.

Note: Using the Email Copy feature is not the same as the CC option. The email addresses entered under Email Copy will receive copies of every email sent, as this feature is intended for archival purposes.
