Did at&t buy yahoo mail

A great question!

In 2017, Verizon acquired Yahoo's core internet business, including Yahoo Mail, for $4.48 billion. The deal was announced in July 2016 and completed in June 2017.

As part of the acquisition, Yahoo's email service, including Yahoo Mail, was merged with AOL Mail, which Verizon had acquired in 2015. The combined email service was rebranded as AOL Mail, and Yahoo Mail was eventually phased out.

In 2020, Verizon announced that it would be merging its media and technology assets, including AOL and Yahoo, with those of Apollo Global Management, a private equity firm. The deal was completed in September 2021, and the combined company was renamed Yahoo.

So, to answer your question, AT&T did not buy Yahoo Mail. Verizon acquired Yahoo's core internet business, including Yahoo Mail, in 2017, and later merged it with AOL Mail.
