Primary, the problem we resolve with Dynamic Yield is to be able to offer personalization capabilities to websites/apps at scale. Historically, being able to provide personalization capabilities to websites like what Amazon does was, let's say, challenging and not cheap.
With Dynamic Yield, you can add a lot of personalization capabilities like recommendations modules based on the user affinity to specific products or send emails based on user actions like abandoning the shopping cart.
Also, to apply personalization at scale, the tool helps you to find hidden personalization opportunities within your campaigns, highlighting variants that perform best for a given audience even if the variant is not the winner. Review collected by and hosted on G2.com.
