Track Twitter activity through email
NutshellMail is a social networking management tool that combines the best of the social web with the original killer app: email. While other social networking management tools require you to download software or to log into yet another website, NutshellMail transforms your existing email inbox into a single social web command center. NutshellMail makes sure you never miss the information you care about by consolidating and organizing your notifications into an interactive email digest delivered directly to you on a schedule you define. With NutshellMail, you can even update your status, reply to friends’ posts, share stories, send tweets and so much more directly through your email inbox.
NutshellMail is part of the fbFund REV incubator program, a joint venture between Facebook, Founders Fund and Accel Partners to seed and incubate early stage companies.
