Yahoo! offers a wide range of products including email, instant messaging, and groups. Each of these products may occasionally have issues that you can't resolve without some customer service help. There are multiple ways that you can get in touch with the Yahoo! Customer Service team, both directly and indirectly.
Yahoo! Contact Us Product Selection Page
The Yahoo! Contact Us Page at https://io.help.yahoo.com/contact/index?page=home&locale=en_US offers customer service help for all the Yahoo! products. Available help categories include: Account, Answers, Aviate, Finance, Flickr, Games, Groups, Mail, Messenger, Mobile, Postmaster, Search, Sports, and Wallet. Some of the Yahoo! products, such as email, require the completion of a form to gain support. If you are having issues with your account that require personalized customer service attention, this may be the best gateway to use. However, this page can be challenging to use if you are trying to get phone or direct email contact with Yahoo! Customer Service. The graphical interface may try to route you to help pages that don't allow for direct contact. When using free Yahoo! products, you may need to attempt contact through both this page and other avenues.
Yahoo! Customer Care on Twitter
The Yahoo! Customer Care account on Twitter, https://twitter.com/yahoocare, can be accessed through Direct Messaging. This may be a good option if you have not been able to resolve your Yahoo! issue in another way, and it can be a good backup measure. For example, if you have already contacted Yahoo! via the Yahoo! Contact Us Product Selection Page and are currently waiting for a response, you may want to Direct Message them on Twitter as well.
Yahoo! Customer Care Page on Facebook
The Yahoo! Customer Care Page on Facebook, https://www.facebook.com/YahooCustomerCare, can be a good contact portal. This page regularly posts updates regarding Yahoo! product fixes, as well. If you have already contacted Yahoo! Customer Care in another way, Direct Messaging on the Facebook page can be a good secondary contact method while you're waiting for a response.
Yahoo! Feedback and Suggestion Site
The Yahoo! Feedback and Suggestion Site at https://yahoo.uservoice.com/ is designed as an area to leave feedback and suggestions regarding Yahoo! products. When you post a suggestion or feedback, other Yahoo! users will be able to see it and make comments. Yahoo! Customer Care will often comment on your statement to let you know whether they are aware of the issue and if a fix is being worked on. This site is a good place to check before you submit an inquiry on the Yahoo! Contact Us Product Selection Page, since the issue you're having may be a widespread one that Yahoo! is aware of and is currently resolving. Another site where users can find information about Yahoo! product issues is Yahoo! Help Central at http://help.yahoo.com/l/us/yahoo/helpcentral/.
Yahoo! Mail Quick Fix Tool
The Yahoo! Mail Quick Fix Tool, https://help.yahoo.com/kb/mail-for-desktop/SLN25558.html?impressions=true, allows you to scan your Yahoo! Mail account for issues. When problems are identified, the Quick Fix Tool will automatically resolve them. To use the Quick Fix Tool, you will need to provide an alternate email address in case Yahoo! can't contact you at the account being scanned.
