Forbes: Google developing ad service for e-mail. Google is clearly moving towards more email services. They added a service to send news articles via keywords awhile back and …Google last year purchased an e-mail management software maker and in 2001 registered the domain name googlemail.com.. I hope they don’t go the route of MSN and Yahoo, because those sites are more about services than relevant search results. The thing that makes Google so attractive is the relevancy of their search results. If they get too distracted with offering a zillion other services. Some in Silicon Valley also believe Google could be preparing to launch free e-mail to compete with offerings from Yahoo and MSN’s Hotmail. Ever wonder how many free email services can co-exist?
