Summary: It's possible to send email to someone without having their email address show up on the To: or Cc: lines by using Blind Carbon Copy or Bcc.

How do I hide the email addresses I'm sending to on a message?

Have you ever gotten a piece of email where you weren't listed as a recipient? Your email address wasn't present on either the "To:" line or the "Cc:" (Carbon Copy) line, but somehow you got it anyway. What you didn't see was what's called the "Blind Carbon Copy" line, or "Bcc:" which allows the sender to specify a list of people to get the message without their name appearing on it.

Why "carbon" and what's this about it being "blind"?

The term "Carbon Copy" dates from the pre-photocopy typewriter days where the way to make a second copy was to insert a sheet of carbon paper between two sheets of typewriter paper - when the typewriter struck an image of a letter on the top, it would also press an image through the carbon paper onto the second page.

"In today's digital age, the term simply means any copy of a document or email sent to someone in addition to the primary recipient."

In today's digital age, the term simply means any copy of a document or email sent to someone in addition to the primary recipient. It's common courtesy on business correspondence to let the recipient know who else is getting the document by listing them after a "Cc:" somewhere on the document. Email of course does this automatically with the "Cc:" field into which you enter email addresses.

"Blind" simply means that someone else gets a copy but they're not listed on the "Cc:" line as getting one.

Here's the rub: how you access the blind carbon copy function will depend on your email client. Look in the on-line help for "bcc" or "Blind Carbon Copy". In Outlook, there is a BCC field that's simply not visible by default. When you compose a message hit the View menu and you'll find an item labeled Bcc field which will turn it on. In Outlook Express, hit the View menu while composing a message and you'll see an item All Headers that does the same.

BCC can be a courtesy if used correctly. If you're sending email to a large number of people you can reduce the size of the message and the "To:" or "Cc:" headers that people might have to wade through by BCCing your message to them. On the other hand, it can also be somewhat rude to BCC what someone might think is a personal message to others as well.

BCC. Use it responsibly.

The solution to a personalized message without a long Cc list is to use a mail merge program like PC iMail (http://www.prosoftapps.com/pcimail). It will let you add mail merge fields such as "Dear [FirstName]" and will insert each recipient's name in the message, and it will also send the message individually to each recipient for a personalized touch.

The other issue these days is the limitations many ISPs place on the number of messages that can be sent in a given time period. My ISP limits me to 25 messages per minute, and so PC iMail's time delay feature helps out by letting me specify the number of messages that will be sent for a given time interval (e.g. Send 20 messages every 60 seconds).

Hi Leo,

had the same question as someone before:

"Good afternoon.
I would like to know if there is any trick in Outlook to Hide my e-mail address once I send an e-mail from my outlook.
If there is such a feature I would also like to know if instead of my e-mail it would be possible to appear "Customer Services" or something like that.

Thank you very much for your answers and tips!

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Yes and no.

You can change the "From:" address on email you send. This article covers that:
http://ask-leo.com/how_do_i_send_mail_from_my_mail_forwarded_address.html

However that does not *hide* you. Your actual email address may still be in
the mail headers, as may be the IP address from which you're sending email.

How do I see who I've sent an email to once it's been sent bcc? Want to check and be sure I didn't already send it. Thanks.

Hello,
there is a webpage, www.emailhide.org, that encrypts your email address in a secure manner. All you nedd to do is type in your email address and is returned html code with a link with your encrypted email. I've tried and now i use it everytime. There's also a automatic gen for webmasters. Check it out.

While interesting, that has nothing at all to do with what this article is about.

If i need to send out a message to a lot of people, but i want them to only see their own name on the email, as if i personally sent it to just them and not 25 other people as well, how would i do this in Microsoft Outlook?

The only way to do that is to send 25 individual emails. You can do that yourself, or you can use a mailing service like aweber.com.

I have gmail and I've tried everything in the book to prevent my mail recipients to see other's addresses, but it won't work. I use the BCC feature but the addresses still show. I know this because I tried sending a message to multiple recipients, where I put one of my other mails in the TO box and the rest in the BCC box. That's when I found that the addresses were displayed.
Thank you very much for your help.

If you're looking in your own sent mail, then they may still be there, since you're allowed to see what you sent. You need to check the actual email received by one of the people getting the email in their account. I'll bet the BCC line is not visible there.
