Initially, eTrigue was chosen amongst other marketing automation tools (circa 2010) to fill the roll of automating several long-term drip nurturing campaigns related to trial-version requests of our software. But it has become much more. Dubbed both a marketing tool AND a sales tool - it took a while for our sales guys to warm up to the features, but now all of Marketing, Business Development, Sales, and the executive management use eTrigue's DemandCenter in some fashion. It addresses many issues, but to choose just one for each department: Sales - many of our customers & prospects work in the field for some of the day, it's handy for the sales person to know (in real-time) when that person is back at their desk and browsing our websites or opening our emails. Bus. Dev. - it's a great tool for tracking the activity/participation of our partners & dealers. Mgmt - we pull information from DC fairly often that helps us make decisions. Marketing - obviously, the automating of messages. But it's more than that; it's allowed us to expand our email marketing efforts 3-5x with the same man-hours.
