You can check your Yahoo! Mail in an email client like Outlook or Thunderbird by signing up for Yahoo! Mail Plus.



Yahoo! Mail Plus is our premium Mail service. It has twice the message size limit (20MB) and comes with AddressGuard (for those moments when you want an email back, but you don't want to give out your real address).



If you have Yahoo! Mail Plus, here檚 how to use it to POP your Mail into another client: the link below is for signing up, paid subscription and set up instruction details

After you finish signing up and filling out the paid subscription details
