You might have been directed to this page because you have sent an e-mail with several e-mail addresses in the To-field when you should have used the Bcc-field.
What is the difference between "To" and "Bcc"
(Blind carbon copy)?
When you add addresses into the To-field,
everyone who gets the e-mail can see everyone else's
When you add adresses into the Bcc-field, no one can see
who else get's the e-mail.
Why was it wrong to use the To-field?
You have breached people's
privacy and put them to risk for
spam and viruses.
1. The people on your list don't want the others to get
their address. They gave it to you only.
2. If even just one person of those you e-mailed gets an
e-mail virus, every person on that list is in risk of
getting it. E-mail viruses check for all addresses that
person has in his/her e-mail.
3. One of the people you send to might be a spammer, or
just send the whole list to someone who sends spam.
4. Someone among the recipients might start sending
advertisements to everyone and not even realize that it is
5. There is a very high risk that someone chooses "Reply to
all" and send his/her reply to everyone on the list. This
can quickly become loads of e-mails to everyone on that
What's the alternative?
If you had put everyone's addresses in the
Bcc-field instead, all these risks would have been
eliminated. What is the Bcc-field?
Never ever use the To-field if you're e-mailing
people who don't know each other, or more than 5-10 people
at a time, use the Bcc-field instead.
