marketing as the buyer 's journey , which can be divided into 3 stages: exploration, consideration and decision. At what point is the contact in that process? Perhaps they have identified a problem or an opportunity, but are still trying to see where they are (exploration).
It could be that they have taken a step further and are already comparing different types of solutions for that problem (consideration). Or it is possible that phone number list they already have a clear idea of what they want and are looking for a specific provider (decision). Each stage requires different messages and content. It is not good to put too much pressure on someone who is not yet ready to buy, in the same way that it does not make sense to offer too much generic information to someone who already knows what they need and who only has to decide who they are going to buy it from.

Contact lifecycle . Addressing a lead who barely knows your company and for whom you have almost no references is not the same as addressing a client with whom you work (or have worked) for months. Even if they fit the same buyer persona and are at the same point in the buyer's journey, they may require a different lead nurturing strategy.
Previous actions of the contact .
This is another of the most common segmentation criteria. For example, a classic strategy is to develop a lead nurturing campaign based on a specific action: what has that user downloaded from your website? What pages have they visited? In the case of lead nurturing, it is closely related to so-called behavioral emails, those emails based on the behavior and interactions of contacts with your brand. Think about the next logical steps, what could catch their attention based on the content they have already shown interest in.
