A pretty big Internet marketing company. However, their business model is slightly different from the rest of the pack - they deal mainly with small businesses, associations and non-profit organizations only. You won't find them working with big name corporations. They are experts in email marketing, event marketing, online survey and social network marketing. They have released numerous tools to help users to make good use of the ever popular social networking phenomenon. They claim that they have over 450,000 small scale customers. I don't know whether that is true or not, but judging by their popularity, they must be doing something right. They are certainly one of the top innovators in the social media marketing segment.
