Now that the amazing email client Sparrow has been acquired by Google, competitors are trying to move in and pick up some of its users. Sparrow’s team won’t be adding any new features, but one company, Postbox, is.

The company decided to buy a promoted tweet to try and lure some folks to leave Sparrow:

In all of its promoted glory:

It’s a pretty wise use of marketing dollars, I have to say. This is what Postbox had to say about today’s news:

Why are so many desktop email clients calling it quits on the innovation front? Is this due to a massive and sudden migration from desktop email to webmail? We don’t think so.

Sparrow focused on providing a Gmail-like experience for Mac desktops and mobile. Google knows that email is important, and they needed to make Gmail on mobile devices better, so hiring the Sparrow team to work on Gmail or “other projects” seems logical.

Thunderbird was having a difficult time supporting Mozilla’s mission of keeping the Web open and free, or at least in ways that had similar impact to Firefox.

From our perspective, we’re seeing more demand for desktop email than ever before. The desktop enables Postbox to provide a unique and powerful email experience, on both Mac and PC, for serious email users who require a high level of usability, integration, privacy, and control.

Trying to grab users of a newly acquired service has become a bit of a trend, with Pocket recently offering an import tool for Facebook’s latest acquisition, bookmarking service Spool.

So if you’re serious about mail on the desktop, it might be worth it to give Postbox a try.
