i worked in a organisation in which we have to send 3000-3500 emails once in a month. I tried it on google email but they blocked my email ID stating junk mail type activity.
We send office documents once in a month by sending 3000-3500 email at a one shot.
I googled on a net and found we need a email server for this type of service.
So kindly suggest me a good free email server with which we can sent 3000-3500 email in day.
