If you already have a pretty large database, you also likely have some contacts that have gone quite stale. If so, I recommend running a re-engagement campaign that can help you both scrub your list and prevent the kind of spam and IP issues I addressed earlier, as well as reawaken old contacts that might have forgotten about you, but would actually be great fits for sales.
Dynamic segmentation – As alluded to earlier, you can’t just send out a generic message to everyone on your list. While basic demographic data can be used to segment your list, that’s far from taking the dynamic approach. Automation tools can help you segment your list as they go through the funnel, allowing you to send personalized messaging depending on their actions and behaviors.
