Infusionsoft is one of 65 companies chosen by VentureBeat to launch at the DEMO Spring 2010 event taking place this week. These companies do pay a fee to present, but our coverage of them remains objective.

Email marketing can be a great way for small businesses to target a specific group of potential customers. Looking to bring advanced email marketing features to the main stage, Infusionsoft today announced the launch of its Email Marketing 2.0 services with several advanced features.

Infusionsoft’s Email Marketing 2.0 services targets small businesses with 2 to 25 employees who are looking to bring their email campaigns to the next level using special software. The service automatically responds and adapts to customer feedback, helping to optimize campaigns and making the possibility for increased sales and customer service more of a reality. Infusionsoft gives small businesses a one-stop shop for email services, including customer databases and the ability to send multiple forms of messages like postcards or voice messages. A new authoring tool will allow users to customize emails based on any uploaded image or company logo, creating HTML emails without messing with code.

A whole host of marketing companies exist that can help you to optimize your email campaigns and keep tabs on a evolving customer base, including Constant Contact and CRMSugar.
