How to send email to multiple recipients without them knowing in Outlook?

Author Xiaoyang Last modified 2025-08-15

When sending group emails in Outlook—whether to clients, colleagues, or subscribers—privacy matters. If you add multiple addresses to the "To" or "Cc" fields, all recipients can see each other’s contact information. This can look unprofessional, or worse, breach confidentiality. To keep recipient addresses private, Outlook offers a couple of reliable solutions. In this guide, you'll learn two effective ways to send group emails in Outlook without showing recipient information:

Method 1: Send Group Emails in Outlook Using Bcc to Hide Recipients (Basic but Limited)

Method 2: Send Group Emails in Outlook with Kutools’ Send Separately Feature (Simple & Private) 👍

Method 1: Send Group Emails in Outlook Using Bcc to Hide Recipients

Outlook's built-in Bcc (Blind Carbon Copy) feature allows you to send the same email to multiple recipients while keeping their addresses hidden from one another.

1. Click Home > New Email to open a blank message window.

2. Go to the Options tab and click Bcc to make the Bcc field visible.

3. In the To field, enter your own email address. And in the Bcc field, add the email addresses of all intended recipients.

4. Compose your message and click Send.

📌 Result: Each recipient receives the same message and sees only your email address—all other recipients remain hidden, preserving privacy without personalization.

⚠️ Limitations of the Bcc Method:

❌ Impersonal: Recipients can tell it's a mass email.
❌ No tracking: You can’t view responses by recipient easily.
❌ No personalization: All content is generic.
❌ Risk of error: Forgetting Bcc exposes recipient addresses.

Which Method Should You Use?

Here's a side-by-side comparison to help you decide:

Method	Best For	Ease of Use	Efficiency	Recipient Privacy
Outlook Bcc	One-time use	⭐⭐⭐	⭐⭐	⚠️ Hidden, but not foolproof
Kutools Send Separately	Frequent or professional group emails	⭐⭐⭐⭐⭐	⭐⭐⭐⭐⭐	✅ 100% private, individual delivery

Conclusion: If you’re sending one quick email and don’t need personalization, the Bcc method works fine. But if you value privacy, professionalism, and efficiency, especially when emailing clients or teams, Kutools for Outlook’s Send Separately feature is by far the better option.
