How can this Gmail and Yahoo afford to give Free one GB mail box?
First off, they advertise, advertise, advertise. As well, they make money with some companies by allowing some junk mail to bypass the Bulk filter and end up in your inbox. Another thing is that these companies know that most email users wouldnt even use HALF of the 1GB storage, for example i only use 2MB of the storage. Although they say they have 1GB storage per user, they dont actually carry 1GB storage per account made. And the cost on 1 GB these days is about 50 cents max, so giving you 1GB storage for 50 cents and earning back a few hundred dollars from an advertisement still yields profit.
Reply:Advertising!! Read the privacy rules VERY carefully...they do share some information that companies think is very important!
