A new Yahoo Mail was introduced not a long time ago. After spending several months in beta, Yahoo started rolling it out to all users, though it was still mostly opt in. Even so, it has now managed to get 100 million users to switch to the new design.

"We’ve reached two major milestones with over 500,000 fans on our Facebook page, which was the most explosive page on Facebook in June, and more than 100 million monthly active users in the newest version of Yahoo! Mail!," Yahoo announced.

While there have been some complaints, especially about the fact that once you upgrade to the new Yahoo Mail, there's no going back to the older version, unless you want the ancient Yahoo Mail Classic version.

While this criticism may be warranted, it's important to note that at least Yahoo is giving users a choice, albeit a limited one.

Other companies, Google for example, regularly roll out new versions and upgrade everyone to them, no questions asked.

That said, if you do have issues and problems with the new Yahoo Mail, Yahoo would love to hear about it. And, if a lot of people complain about the same thing, they may even read your feedback post.

"The 'feedback loop' begins when you write to us about the things you love, the things that you would like us to change, or ideas you would like us to implement," Yahoo explained.

"You can do this by clicking on the 'Send Feedback' link in the help drop down and sending us a line or two about the problem/issue/feature you want us to look into," it added.

Yahoo says it gets about 5,000 pieces of feedback every day, so it has an automated system which sees if certain keywords show up more often.

This enables the team to know what to focus on. For example, based on feedback, Yahoo Mail got a message toolbar at the bottom of the message as well.
