What is BCC in an Email?
The full form of BCC is Blind Carbon Copy. BCC in email is the part of an email that helps in hiding email recipients. This is where you put multiple recipients’ email addresses, and by doing that, all the recipients will be unaware of who else has received the email. Plus, they won’t be able to get the “reply all” replies. Almost all the popular ESPs, such as Gmail, Outlook, Yahoo, etc., have this option for their users to help send a mass email and hide recipients.
Why Should You Hide Email Recipients?
Before walking through the tutorial part of how to hide email recipients in email, you should know about the essential reasons behind doing so first. Let’s learn about the 5 reasons and benefits to hide email recipients.
To protect recipients’ privacy
The first prime reason for hiding email recipients is to protect the privacy of all the recipients. The BCC in an email option prevents showing everyone’s email addresses, and this way, it shields their privacy. In the third quarter of 2024, around 29.9% of internet users worldwide voiced worries regarding company’s misuse of their private or personal data. Hence, hiding email recipients is vital; you have to make sure your users’ email addresses remain hidden.
To maintain professionalism
Hiding recipients in emails gives your email a more professional and polished look. Especially for formal and work emails, you need to maintain such professionalism. It shows good email etiquette.
For confidentiality and discretion
Some situations might require confidentiality and require you to discreetly include someone or others in email. In such cases, you have to keep your email recipients hidden.
To avoid spam
ESPs often suspect multiple visible recipients as spam. Therefore, hiding email recipients can help avoid spam filters and improve email deliverability.
Email marketing
You need to keep your leads’ email addresses or identities hidden for email marketing. To run marketing email campaigns, you must send emails in bulk. For email marketing, it’s better to use an email marketing platform rather than an ESP. You can easily keep your email list or recipients hidden and maintain email compliance regulations using an effective email marketing platform like MailBluster.

Solid Solution to Hide Email Recipients for Email Marketing & Mass Emailing
Are you willing to do email marketing and now looking for ways on how to send mass email without showing recipients? Here, let’s learn how to send an email to multiple recipients individually in email marketing.
There’s an easy option to do that. The most reliable and solid solution to hide email recipients for email marketing and mass emailing is to use an effective email marketing platform/tool. Why not use ESPs for email marketing? Well, let’s see why:
- Email marketing requires you to run email campaigns in bulk. Sending bulk email using an ESP like Gmail or Outlook will be a hassle as you will have to insert each email address from your email list separately and manually every time. However, using an email marketing tool, you just need to craft a suitable email template and then simply send it to multiple recipients individually while keeping their email addresses hidden.
- Also, ESPs have limitations and requirements for bulk emails. It’s not at all a good choice for large email lists. For example, using Gmail, you can send only 500 emails per day. If you want to increase the limit, then you have to upgrade to Google Workspace. So, there’s not really a smooth way for you to send mass emails with hidden recipients. But, using a handy email marketing tool like our MailBluster, you will face no such issue with email sending limitations. You can easily send millions of emails while keeping the recipients’ email addresses hidden with it.
- Also, no BCC hassle here! All your emails will be sent individually without manual BCC set up.
