Yahoo! continued to provide Telecom's email service, which came under criticism in early 2013 following a spam and phishing attack described as the biggest to have ever hit New Zealand. Telecom automatically reset thousands of users' passwords. In April, Telecom announced that despite the issue, it would keep Yahoo! on as an email provider.
