"Drip marketing" is a term used online a lot, it refers to what agencies or more traditional marketing strategists would refer to as "customer life cycle management". The big idea here is to consistently deliver value to your list of leads or customers. The obvious impacts are: 1) you get a message in front of your users regularly (ie... you stay top of mind) 2) if they are engaged by what you have to share with them and they value the content, they view you as a go-to expert on your area of specialty (ie... they know you, like you and trust you) The long-term impacts of "drip marketing" or "customer life cycle management" are even more pervasive and impactful than this. Sadly, far too many business view providing a quality product or service as the primary source of customer retention... it isn't. Bottom line: consistently being viewed as a respected source of VALUE isn't just an effective way to retain users & customers - it's really THE ONLY WAY.
