Shutterfly and Dell are partnering to drive ROI through directed content and personalized communications. Testing showed targeting messaging and trigger cadence based on customers' first purchase can increase response rates by 48-700% and revenue per mailed piece. Lessons learned are that the welcome period is a time period, not a campaign, and analysis needs to be over the full period. Shutterfly provides end-to-end direct marketing solutions for Dell including creative development, production management, and using data to deliver personalized communications.
