Yahoo has just bought up inbox management tool Xobni.
For now, many of Xobni's products will remain available until at least July 2014, though the company is no longer accepting new purchases of premium products.
Xobni did not elaborate on how it will integrate with Yahoo, except to say that Yahoo "want[s] us to use our platform to make many Yahoo services better for you." The Xobni team is currently moving from San Francisco to Yahoo's Sunnyvale headquarters.
"Did you ever meet someone who truly 'gets' you? That's how we feel about Yahoo," Xobni said in its statement. "The power within every Xobni product is that it responds to how you communicate. Every day you demonstrate who and what is important to you. That can benefit not just your inbox or smartphone, but the many services you use. Yahoo gets that."
According to All Things D, the deal is worth about $30 million (£20 million).
Xobni has a lengthy FAQ on its site that you can check out to see if and when your favourite Xobni product will get the boot.
Xobni - which is "inbox" backwards - started in an MIT dorm room back in 2006, when co-founder Adam Smith wanted to analyse data in his Outlook inbox. Matt Brezina joined the effort and with some funds from Y Combinator, the duo relocated to San Francisco to launch their startup.
Xobni for Outlook debuted in 2008, which promised to speed up the search process within Microsoft's email service. At the time, Xobni held acquisition talks with Microsoft, but talks eventually broke down over price, independence, and requests that Xobni employees relocate to Seattle.
A premium version of Xobni was introduced in 2009, and it expanded to Gmail, Android, and iPhone - as well as app stores - by 2011.
Yahoo, meanwhile, revamped its mail service in December, shutting down classic Yahoo Mail for an offering that it said is speedier, "more intuitive, and easier to navigate."
Under the direction of CEO Marissa Mayer, Yahoo has been on an acquisition streak. It recently shelled out $1.1 billion (£720 million) for blogging platform Tumblr, but has also made a number of smaller purchases, like video app Qwiki, iOS photo-editing app maker GhostBird, and enterprise conference calling service Rondee.
