At the present time, we cannot find customer service phone number for Yahoo Mail that you can contact for email support. However you can contact them via Twitter @yahoocare or via their help webpage: http://help.yahoo.com/
As far as email goes. Yahoo Mail is one of the best. They have certainly been around far longer than many of their contemporary rivals – after all, Yahoo was one of the first companies to ever categorise the entire internet, creating a sturdy email client was just a logical progression for them.
Yahoo!’s signature purple colour has become very familiar to millions, if not billions of users, worldwide. Though, this default setting can easily be changed if you want a more personalised look for your email. Even though Yahoo has a great product, there will still be some instances wherein you would want to contact their support team.
