I just downloaded and installed the program, I do a daily group mailing. Is there anyway to create a group and send to them all at once
Yes, just create a distribution list and add contacts of that group. You can do it by clicking on New button in toolbar and then select Distribution list.
Is there a way to hide the group-members in the send E-Mail?
I just don’t want everyone from the list to have all the E-Mail-adresses.
with email, recipients of a message are specified using addresses in any of these three fields:
To: Primary recipients
Cc: Carbon copy to secondary recipients—other interested parties
Bcc: Blind carbon copy to tertiary recipients who receive the message. The primary and secondary recipients cannot see the tertiary recipients. The tertiary recipients can only see their own email address in Bcc.
