I am needing to send out 400 e-letters per month at one time and Yahoo and other webmail accounts I have started limit me to 50 or so. I have an account with yahoo groups now that helps this. I can send out e-mails to everyone at one time. The problem I have is that I cannot synchronize that Groups addressbook with my tbird address book. I cannot select only 30 or 40 people from all the people in the group to send e-mails to. Is there some way around this? i would really like to be able to send hundreds of e-mails at one time from my account. is this just dream?
