Constant Contact Buys Social Network Aggregator NutshellMail

Constant Contact, which provides online marketing tools for small businesses, is making a social network aggregation play, buying up NutshellMail, which is taking a seemingly more traditional approach to the “social networking overload” problem that many companies are trying to solve. Rather than centralize social network updates via a new client (like Nomee) or a new site (like Microsoft (NSDQ: MSFT) is doing with Spindex), NutshellMail simply sends its users all of their updates via a very customizable e-mail digest.

Constant Contact — which provides e-mail marketing, event marketing and online surveys for small businesses — is pitching the product as an easy way for small businesses to keep track of what people are saying about them online.

Financial terms were not released. NutshellMail had been a member of Facebook’s fbFund REV incubator program. Publicly traded Constant Contact raised about $90 million in an IPO in October 2007. More details in the release.
