I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

"Undisclosed Recipients" only works for those who you send an email to.
When they receive your email and read it. They will see its from you, but not see everyone else whom it was sent to.

You cannot make your email address (Senders Email Address) Undisclosed
