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

Home » EMail

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. 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.

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

You probably already know this, but what should a
person do to send a BCC if their e-mail doesn't
show BCC in the TO field? ANSWER: Usually your
e-mail will have a CC blank. In this space, list
the outgoing e-mails with a parenthesis "("
before the first and a ")" after the last e-mail.
I learned this when I had an account with JUNO.
Their outgoing mail has no BCC.

ALSO, when attempting to send e-mail to
UNDISCLOSED-RECIPIENTS, many e-mails REQUIRE a
domain. Thusly, you must address the e-mail to
UNDISCLOSED-RECIPIENTS@yahoo.com, or the domain
you are e-mailing from. Naturally, you'll get a
'unknown' e-mail back saying it couldn't be
delivered. However, all of the 'OTHER' e-mails
will be delivered.

Keep others from knowing who SENT the e-mail?

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-----

Yes and no.

You can change the "From:" address on email you send. This article covers that:

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.

you can use free online services such as www.anonysend.tk to do so.. saw this one on a flyer at my university and it worked for me so thought i'd recommend it.
