Yahoo Mail Classic has shut down, formally making way for the new version of Mail, which launched six months ago.
The Internet giant announced the discontinuation in April, warning users that beginning 3 June, Yahoo Mail Classic and other versions of the web-based mail services would no longer be available.
The upgrade made headlines because the new Yahoo Mail uses a scanning technique currently in place on services like Gmail, which will serve up ads based on the content of your inbox.
To opt out of the advertising, users can update their settings online using the Ad Interest Manager.
Meanwhile, for those who do not want to embrace the new Yahoo Mail, Yahoo suggested accessing messages via IMAP, which will let you have Yahoo Mail messages delivered to another email provider. Or, you could just close your account.
In April, the company announced it would shutter products like Yahoo Deals, Yahoo SMS Alerts, Yahoo Kids, and older versions of Yahoo Mail, most of which were closed by 30 April.
"We want to bring experiences that inspire and entertain you every day," Yahoo said in an April blog post. "That means taking a hard look at all of our products to make sure they are still central to your daily habits."
Apparently Mail Classic was no longer a daily habit for enough people that the company could justify turning it off, in favour of the new version of the email service.
"We realize that change is hard," the company said at the time, "but by making tough decisions like these we can focus our energy on building beautiful products for you."
Meanwhile, Yahoo recently launched Yahoo Mail for iPad and Android tablets, as well as Yahoo Weather for iPhone.
