If you want to send the same email to multiple people without revealing everyone’s email address, there are a few ways to do this. This guide will show you how to send the same email to multiple recipients separately in Gmail and Outlook, as well as why you might need a specialized service for that.

Why send mass emails without showing recipients

There are a number of reasons you might need to send an email to multiple contacts without them knowing who else is receiving the message. Salespeople may want to get in touch with their clients and prospects, while marketers might need to run email marketing campaigns  to reach a wider audience and promote their products or services. Similarly, recruiters may need to update applicants or organizations on open positions.

The main benefit of hiding the entire list of recipients is that it creates the illusion of a personal email, rather than a mass-sent one. This often leads to higher engagement rates and less chance of ending up in the recipient’s spam folder.

Hiding someone’s contact information is also a way to make them feel safe and secure.

How to send an email to multiple recipients individually in different clients

If you want to send an email to multiple people at the same time, you can use either the Cc or Bcc option.

Bcc and Cc lines in email

Adding someone to the Cc (or Carbon Copy) list means that they will receive a copy of the email that is sent to the original recipient. However, everyone on the Cc list will be able to see who else is receiving the email.

Bcc stands for Blind Carbon Copy and it allows you to send an email to multiple recipients without them knowing who else is receiving the email.

Although the Bcc option allows you to send emails without any recipient knowing, the email is generic and does not allow customization.

You can send mass emails without revealing all the recipients by putting them in the Bcc line.

How to send a mass email and hide recipients in Gmail

To send an email with hidden addresses in Gmail, follow these steps:

  1. Click the ‘Compose’ button.
  1. The To’ section is where you enter the email addresses of the people you want to receive your message. If you want to keep the email addresses of your recipients private, you can either leave the ‘To’ field blank, or enter your own email address.
  1. Click on ‘Bcc’ (top right) and enter the addresses of other recipients, separated by commas.
  1. Write the email and send it out. That’s all. Your contacts will not see each other.

How to send mass email individually in Outlook

  1. To start a new email in Outlook, click on the blue ‘New Message’ button in the top-left corner of your screen.
  1. To add people to the Bcc field, start by clicking on the Bcc link at the top of your email editor.
  1. Then, in the ‘To’ field, add your own email address. In the ‘Bcc’ fields, select or type in the email addresses of all the recipients. See screenshot for reference:
  1. When you are finished writing your email, click the ‘Send’ button to send it.

Challenges to be ready for

When you use the Cc or Bcc methods to send emails to multiple people, there may be some downsides:

The emails may be considered spam

Sending an email to multiple people at once using the Cc or Bcc methods may trigger spam filters. If you use email tools that aren’t designed for mass emails, your emails could end up in the recipient’s junk folder — or worse, never make it to their inbox at all. To avoid this fate, follow these simple tips on how to stop emails from going to junk.

The number of addresses may be limited

Some email services have a limit on how many addresses you can include in a bulk email to prevent possible fraudulent activity. For example, Gmail limits you to 500 addresses per email, while Outlook caps the number at 5000. The number of email addresses you are sending to does not matter, each message counts towards the limit. If your contacts list exceeds the limits, you will need to take a break and return to the mailing the next day.

Recipients can reply to all

When someone hits “Reply all” to a Cc email, everyone on the list will get that reply. This can quickly become annoying for people who are not interested in the conversation. 

But it won’t happen to those contacts who are on the Bcc list. If you are a Bсс recipient of an email, by hitting the “Reply all”, you will only reply to the original sender and any contacts in the To’ field. The other Bcc recipients will not see the reply.

It looks unprofessional

The Bcc method is not practical for professional mailings because the recipients can see that they have been added as a Bcc object. This looks unprofessional and might leave a bad impression on your clients and partners.

The way out

When sending an email to multiple people, it is best to only use the Bcc feature and email services like Gmail sparingly. If you need to communicate with a lot of people on a regular basis, it’s better to use a free bulk email service like Selzy.

The best services to send emails to multiple recipients without them knowing

There are email marketing services (ESPs) that can help you target your audience better than using a regular email account. These services have features to help you measure your results, and you can easily send out mass marketing emails without having to use the Cc or Bcc options, and without any other limitations.

Email marketing services provide a number of advantages when it comes to bulk messaging:

  1. Email marketing services hide your contact list from recipients, so they cannot see who else is receiving the same message. This helps protect the privacy of your subscribers.
  2. You have access to reports detailing the success of your campaigns, including how many messages were sent, delivered, and opened. This helps you gauge the effectiveness of your efforts.
  3. Using a service lowers the chance that your email will end up in spam folders. Services take steps to follow the laws, as well as build a reputation with internet providers and use authentication methods to make sure a sender is legitimate.
  4. Third, email services offer segmentation and personalization features that allow you to send highly customized messages and target your offers to the specific needs and desires of your clients.
  5. Most services provide templates and builders that you can use to create professional-looking emails, saving you time and effort. For example, Selzy provides an easy-to-use email builder that lets you create unique templates without knowing how to code.
  6. You can use email automation tools to send out mass emails, and escape much of the manual work of responding to customers’ actions. With these tools, you simply set up a process once from the start, and it will run on its own after that.
  7. The support teams of email service providers can help resolve any issues that come up. They can help you with things like getting your emails marked as spam, or if you’re having trouble with authentication.

Final thoughts

There are many reasons you might want to email multiple people without letting them see who else is on the list. This can make an email seem more personal, as if it was meant just for them. It also allows you to keep your recipients’ addresses private.

If you are wondering how to send mass emails without showing recipients, the only way to do this in email clients is to manually send emails using the Bcc option. Just keep in mind that Bcc has some limitations, such as:

  • The possibility of being marked as spam
  • The lack of personalization options
  • The limited number of addresses
  • The absence of automation
  • The lack of analytics

In general, it is best to use Bcc sparingly. If you need to frequently send emails to large groups of people, it might be better to use a professional email marketing service. They have many advantages over regular email services, including reports on campaign success, lower chances of triggering spam filters, and the ability to send highly customized messages.
