When I do a mass mailing I really don’t want all the people seeing who I sent the email too. How do I eliminate all the recipients? Thanks for any help.

I am trying to send an email to everyone in my address book. I have about 900 contacts, and it would not be practical to check each one individually. Is there a way to check all addresses and send one email to my entire address book?

I did try the free email of aol using my sender but the emails were not sent.

I normally mass email word doc files using outlook.

I need to send out an email to all my co-workers (only been with the company for 2 1/2 months so not everyone knows me) letting them know that I have changed my name (and email has changed) due to my recent marriage. What should I write? Thanks!!
I was told by my boss to send out a mass email, otherwise I would not do so…which is why I really have no clue what to write
