This guide details the different ways to address an email to multiple recipients, including masking the email addresses of other participants.

Preamble

• When you send emails, it is sometimes necessary to include multiple recipients using the fields:
  • À
  • CC:
    • French: Copie Conforme
    • English: Carbon Copy
  • BCC:
    • French: Copie Conforme Invisible
    • English: Blind Carbon Copy
• Do not overload the To and CC fields with recipients who are not directly concerned by the email.
• Use the BCC field to protect the email addresses of the recipients when there are multiple people on the list.
• For multiple, recurring and/or important sends, beyond the imposed limits, it is recommended to use more appropriate tools instead:
  • Infomaniak Guest Manager
  • Infomaniak Newsletter 

Understanding and using these 3 email fields

The To field

This field is used to indicate the main recipient(s) of the email, those who receive the email as a direct copy.

• Use this field for the main recipients who are directly concerned by the content of the email.
• Examples: work meeting, project report, direct communication with a client.

The CC field

Used to send a copy of the email to other people in addition to the main recipients. All recipients can see who received a copy of the email.

• Use this field to include secondary recipients who need to be informed but are not the main actors in the discussion.
• Example: informing a supervisor about a conversation, including colleagues interested in the subject without them needing to intervene.

The BCC field

Used to send a copy of the email to people without the other recipients knowing they also received the email.

• Use this field to include recipients who need to receive the email without the other recipients knowing.
• Example: sending an email to a group with a supervisor in BCC for follow-up, avoiding the disclosure of email addresses to all recipients (often used in mass emails).

Usage examples

Each of these fields has a specific function and can be used strategically depending on the context of your communication. Be transparent and ethical in the use of the BCC field to avoid misunderstandings or conflicts:

• Team Communication
  • To: main project members
  • CC: Project Manager, other concerned departments
  • BCC: Director for information without direct intervention
• Marketing E-mail
  • To: do not use (or simply indicate the sender's email address)
  • CC: do not use
  • BCC: list of subscribers to protect individual email addresses
• Important Announcement
  • To: main recipients (e.g.: directors)
  • CC: board members, key collaborators
  • BCC: other stakeholders for confidential information
• Meeting Announcement
  • To: John Doe, Jane Smith
  • CC: project.manager@company.com
  • BCC: director@company.com
• Event Invitation
  • To: main guests
  • CC: coordination@event.com
  • BCC: list of secondary guests (to protect email addresses)
