You can use a cold email software or a sales engagement software to send hyper-personalized emails at scale. These tools offer a range of personalization options, from text personalization to image and video personalization. Besides this, these tools help you identify sales-ready prospects allowing you to send personalized sales follow-up emails at the right time. They do this by assigning a buying intent score to your prospects based on how they interact with your emails. That means their intent score increases every time they open your email or click on a link, indicating their sales-readiness.
