Verizon-owned social media platform Tumblr, along with a laundry list of other Yahoo services, is potentially locking users out of their accounts due to an ending partnership between Yahoo and AT&T, according to Techcrunch. If you’re a Tumblr, Flickr, or regular user of any other Yahoo service and have an AT&T-provided email address, it’ll stop working for those sites on June 30.
Like, this Friday, June 30.
Tumblr addressed the email shutdown in a post in its help center:
Starting on June 30, 2017, att.net customers will no longer be able to log in to their Yahoo and Tumblr accounts through email addresses with the following domains: att.net, ameritech.net, bellsouth.net, flash.net, nvbell.net, pacbell.net, prodigy.net, sbcglobal.net, snet.net, swbell.net, and wans.net.
In short, if you want to use your AT&T-friendly email to access Yahoo’s services like Flickr and Tumblr, you’ll need to change your email address and create a Yahoo ID. The change might come as a surprise to AT&T users, who have been able to use their emails to access a variety of Yahoo-branded services despite the non-Yahoo email address.
AT&T provided even more information about the email service termination, including a list of sites affected by the change and instructions on how to switch email addresses inside services that support the email change. Flickr users will have to visit an email transfer page, while Tumblr users can change their email address in their settings page.
Not every Yahoo service will support an email transfer, however, and may require you to create a new Yahoo ID without the benefit of saving your past data. Better hurry.
