How to send an email in outlook without showing recipients

Last Updated: Mar 8, 2024 by

In today’s digital age, privacy and security are of utmost importance. With the rise of cyber attacks and data breaches, it’s crucial to take steps to protect your personal information. This includes your email communications. If you use Microsoft Outlook as your email client, you may be wondering how to send an email without showing the recipients. In this article, we will discuss some techniques for secure messaging and email encryption to help you send emails privately in Outlook.

BCC (Blind Carbon Copy)

The most common way to send an email without showing the recipients is by using the BCC feature. BCC stands for Blind Carbon Copy and allows you to send an email to multiple recipients without them seeing each other’s email addresses. To use this feature in Outlook, simply click on the “BCC” button next to the “To” field when composing a new email. This will open a new field where you can enter the email addresses of the recipients you want to hide from each other.

Email Encryption

Another way to send an email without showing the recipients is by using email encryption. This method ensures that only the intended recipient can read the email, even if it falls into the wrong hands. There are various email encryption services available, such as ProtonMail, Virtru, and Tutanota. These services use advanced encryption algorithms to protect your email communications. Some of these services also offer plugins for Outlook, making it easy to encrypt your emails directly from your email client.

Password-Protected Attachments

If you need to send sensitive information through email, you can also use password-protected attachments. This method involves encrypting the attachment with a password and then sending the password to the recipient through a separate communication channel, such as a text message or phone call. This way, even if the email is intercepted, the attachment will still be protected by the password. To password-protect an attachment in Outlook, click on the “File” tab when composing a new email, then select “Protect Document” and “Encrypt with Password.”

Secure Email Services

If you want to take your email security to the next level, you can also consider using a secure email service. These services offer end-to-end encryption, meaning that only the sender and recipient can read the email. Some popular secure email services include ProtonMail, Tutanota, and Hushmail. These services also offer plugins for Outlook, making it easy to send secure emails directly from your email client.


In today’s digital world, it’s important to take steps to protect your personal information, including your email communications. By using the BCC feature, email encryption, password-protected attachments, or secure email services, you can send emails in Outlook without showing the recipients. This will help keep your sensitive information safe and secure.
