STYLETHREAD -- LET'S TALK SHOP!

I am having trouble with MS Outlook. Let me just say right now that I am technologically inept, so there may be an obvious solution that has not occured to me, but here's the issue:

I keep mailing lists of my customers, and e-mail them when I make web site changes or have upcoming events. What I do is enter the e-mail contacts into Outlook, and then add those contacts into a separate group called "Customers". Then I e-mail myself, and BCC the customers, information about my shows and such.

It appears that even though the sent mail shows up in the "sent" folder, the e-mail is not being delivered to anyone. I am not getting my own copies, nor is my DH (who is on the BCC list), and I did a test with one of my customers and she is receiving nothing from my group mails.

Individual mail is okay, but the group mail is not working for some reason...I'd love to hear any suggestions. I am not going to be able to grow my business if I can't reach the customers who want to hear from me...argh!

TIA!
