How to hide email addresses in distribution list in Outlook?

Author Sun Last modified

When sending an email to multiple recipients, privacy concerns often arise, especially when you don't want everyone to see each other's email addresses. This tutorial will show you two ways to hide email addresses in a distribution list in Outlook: one using Outlook's built-in BCC feature and another using Kutools for Outlook's Send Separately feature, which offers additional flexibility and automation.

Hide Recipients’ Addresses in Distribution List


Hide Recipients’ Addresses in Distribution List Using Outlook's Built-In BCC Field

In Outlook, if you do not want to display the email addresses of the recipients, you can use Bcc.

1. In the Message box, click Options tab, and click the Bcc button to display the Bcc field on the message header.

3. Click OK to go back to message window, send as usual after editing the email.

Now the recipients’ email addresses will be hidden.

Limitations
  • Recipients can see they are in the BCC field, which may seem impersonal.
  • You cannot personalize emails for each recipient.
  • It may not work well for large-scale email distribution, as some email servers limit the number of recipients.
