Dive Brief: 

• Twitter has added new features to improved targeting to the Tailored Audiences program that launched last year. 
• A main feature is that marketers can now share client email lists with Twitter that will match up those CRM emails with users. 
• Advertisers can also now build audiences with Twitter IDs and build lists based on user bios, follower counts, verified status, or past tweets. 

Dive Insight: 

With the pressure on from last year's IPO, any improvements Twitter makes to its advertising offerings is a good move forward. A big problem the social network has faced in the past is being able to provide appealing targeting options to advertisers, but the new Tailored Audiences features solve some of those issues.
