Dive Brief: 

• In an effort to increase ad revenue, LinkedIn is bringing Sponsored InMail to mobile. 
• Now advertisers will be able to send targeted email messages directly to users' mobile devices. 
• Previously, Sponsored InMail would only come to users when they were logged in on a desktop device, but a change was necessary now that half of LinkedIn pageviews happen on mobile. 

Dive Insight: 

Now that an increasing amount of social media and Internet use happens on mobile, it would be foolish for LinkedIn not to have a mobile strategy. The site has covered its bases by allowing potentially annoyed users to opt out of receiving Sponsored InMail. With the mobile push, it will be interesting to see numbers on how ad revenue is impacted.
