We are one of portals promotion company based in India, now we are operating around 12 portals including 6 job portals.
Our portals need large volume mailings ( all are opted list no spam) but we found its difficult to have a server company for this.
We are ready to spend around $300 - $400 per month exclusively for the mail servers ( may be 1 server or a cluster) , we are in need of a good company for this.
Our mail volume is actually too high 100,000 - 200,000 per day normally from all our 6 job portals.
If anyone knows the details do help us for purchasing and now we have servers from 4 diff companies and want to shift this to single company for operational purpose.
