Hi, i need to send many email at once in one click on vb.net, but i don't know how to do that...
simply, i thought like this...
if there is a list of email address in a datagridview..

List :
a@domain.com
b@domain.com
c@domain.com
d@domain.com
e@domain.com

So, I just think that I can use looping as much as Row Count in that datagrid,
and sending the email message for each address in that list...
I think's it's not effective if it's have 100 row count, and i believe there is another way to do that..
but, I can't find out how to do that.. Please, anybody can help me ??
