E-commerce platform SalesOptimize announced the launch of its B2B sales lead generation search engine for companies selling their products or services to e-commerce merchants.

Vocus, a provider of cloud-based marketing software, announced new and enhanced features in its Marketing Suite, which now integrates email, social media, search and publicity.

The  iContact email platform, which Vocus acquired last year, is now fully integrated into the Vocus Marketing Suite. The Buying Signals module monitors social media to notify marketers when customers are ready to buy their product or service. The Business Streams feature provides marketers with a single management point to receive marketing opportunities such as sales leads, media interview requests and social media conversations.

Twitter has announced new features for its web site and mobile apps designed to simplify the process of sharing and finding content.

Users will now have the ability to email tweets more easily from the Twitter web site. The embedded option, which will be available through a new "More" icon next to the existing "Favorite" icon, will open an email window.
