You probably don’t need convincing that personalization is helpful but it’s still nice to proof. The Relevancy Group offers some in a report sponsored by email personalization vendor Liveclicker. Analyzing Liveclicker client results, they found that dynamic email content based on behavioral targeting delivered nearly 8% more revenue, real-time personalization based on open time and context delivered a 13% lift, and machine learning personalization increased revenue by 21%. They also report that 55% of consumers said they like emails with relevant products and offers. The rest are masochists.
