Yahoo! Mail
Yahoo! made a deal with the online communications company Four11 for co-branded white pages. Marvin Gavin, who worked at Four11 as the Director of International Business Development, said "We always had a bias about being acquired by Yahoo. They were more entrepreneurial than Microsoft. We had a great cultural fit – it made a lot of sense." In the end, Yahoo! acquired Four11 for $96 million. The purpose behind acquiring Four11 was the company's RocketMail webmail service, which launched in 1997. Yahoo! announced the acquisition on October 8, 1997, close to the time that Yahoo! Mail was launched. Yahoo! chose acquisition rather than internal platform development, because, as Healy said, "Hotmail was growing at thousands and thousands users per week. We did an analysis. For us to build, it would have taken four to six months, and by then, so many users would have taken an email account. The speed of the market was critical."
UK Mail
It began trading in 2004, with Powergen as its first customer, and delivered its one billionth item of mail in October 2006. In 2009, its parent company, Business Post Group, became UK Mail Group to "reflect the growing importance of the mail arm". In 2015, problems caused by a new automated sorting hub had resulted in a loss in profit, and a share price drop.
In September 2016, UK Mail announced that it would be acquired by Deutsche Post DHL Group. By this time, the news media reported that the company had established "one of the largest integrated parcels and mail operations in the United Kingdom" The sale was concluded in December 2016, for US$315.5 (£243 million).
