Drip marketing is a communication strategy that sends, or “drips,” a pre-written set of messages to customers or prospects over time. These messages often take the form of email marketing, although other media can also be used. Drip marketing is distinct from other database marketing in two ways: (1) the timing of the messages follow a pre-determined course; (2) the messages are dripped in a series applicable to a specific behavior or status of the recipient.
Email. The most commonly used form of drip marketing is autoresponder. In this method, a lead completes the form on a company’s website and is then enrolled in a drip marketing campaign with messaging appropriate to the form’s context.
Direct mail. Although more costly, direct mail software has been developed that enables drip marketing techniques using standard postal mail. This technology relies on digital printing, where low-volume print runs are cost justifiable, and the variable data can be merged to personalize each drip message.
Social media. The principles of Drip Marketing have been applied in many social media marketing tools to schedule a series of updates.
 Lead generation
Drip marketing can be used as a function of the Autoresponders, new leads are automatically enrolled into a drip marketing campaign with messaging relevant to the call-to-action from which the lead came.
Advantages include the automation and efficiency, as well as the continued ability for direct response. Intelligent e-commerce sites, such as Dell, have integrated this form of drip campaign with un-purchased shopping carts. The continued messaging is relevant to the contents that the shopper stopped short of purchasing, and continue to include direct response actions (i.e. buy now).
Disadvantages include the impersonal manner of follow-up. If not augmented with a traditional and personal follow-up method, this automated follow-up has a lower response rate than does personal sales. The lowered response rate is often justified by the volume and efficiency with which leads can be generated and converted.
 Sales process
Drip marketing is popularly applied as a sales tool, particularly in long sales-cycles (large ticket items or enterprise-level sales). Whereas persistent follow-up can become a deterrent to closing the sale, Drip Marketing methods offer the ability to remain top-of-mind, and even prompt action, without jeopardizing the relationship.
