WiseStamp – eMail Signatures Bring Life To Your eMail
http://www.wisestamp.com/

WiseStamp Email Apps enable users to transform their emails into a powerful self expression and promotional tool. Email Apps enable you to easily customize your email signatures with your personal social profiles and allows you to add to each outgoing email dynamic content such as your latest eBay item, recent blog post, your latest tweet or a cause to promote. The recipients of your email will see the updated content of the Email App and will be able to also interact with it directly from the email (e.g. retweet or follow in the Twitter App or buy in the eBay App). This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
