Is is risky to send emails with many recipients in the "To:" heading?

Thanks.

Mac

It can be, depending on the e-mail. If you need to send an e-mail to a lot of people and don't want all the recipients to see each other's e-mail address, you can use the BCC (blind carbon copy) field instead of the To: field. BCC should be supported by all e-mail programs and webmail services.

E-mails can have up to 3 kinds of recipients:

To: The main recipients/targets. Every other recipient can see them.
CC: Like To, but not for the main recipients. Every other recipient can see them.
BCC: Like CC. No other recipient can see them.

An e-mail can have zero or more recipients in any of these fields, but at least one recipient in at least one field is needed.

Andrew,

Thanks for your response. I should have said more. I have long since adopted the procedure you suggest, because someone whose opinion I trusted said it should be done that way. What I'm concerned with now is whether it is worth risking offense to a very nice lady, whom I don't know well, by suggesting that she follow the same advice.

If it's not really a risk, I won't bother her about it, but I'd feel pretty foolish if her whole mailing list got infected with malware because I didn't want to hurt her feelings.

Thanks again,

Mac

Unfortunately using the BCC field won't do anything to protect against malware (but it won't make anything worse, either.) Its sole function is to conceal recipients' e-mail addresses from other recipients.

If you put all the addresses in the to: field - address A, address B, address C, address D, etc and send out the mail, then you have exposed all the addresses to each person on the list. Perhaps person C doesn't want person A to know his address? Or B and D are mortal enemies and neither wants the other to know their address.

It's just common courtesy to use the BCC: field when sending out to a group.
