Email secrets: why it is worth using BCC when sending bulk correspondence?

11 September 2023

An error in the use of personal data is like a scream in a library – everyone turns around because no one expects to hear it. Every year, such errors are among the most frequently reported data protection breaches. The consequences? Often severe, especially when we are talking about sensitive data.

When you send an email, you typically have three fields to enter addresses: "To" (main recipients), "CC" (Carbon Copy), and "BCC" (Blind Carbon Copy).

If you add an email address in the "BCC" field, the person whose address is entered there will receive a copy of the message, but other recipients (both in the "To" and "CC" fields) will not see that address. This is useful when you want to send a message to multiple people but do not want them to see each other's email addresses.

By using BCC, you protect the privacy of the recipients, as none of them can see another's email address. If you plan to send confidential information, you can enhance security by utilizing several additional features.

Try:

  • to establish rules in your email system that will alert you when you are entering multiple recipients in the "CC" field;
  • to set a delay for sending the email (1 minute is sufficient) to allow for corrections before the message is sent;
  • to disable the auto-complete feature so that the system does not suggest email addresses in the recipient field.

Errors in using the BCC function can be as undesirable as loud disruptions in a quiet space. Although BCC is a great tool for maintaining the privacy of recipients, it is worth considering additional precautions, especially when the correspondence contains sensitive information. Key strategies include establishing alerts for multiple recipients, adding a delay for corrections before sending, and disabling address auto-completion.
